Description

WO00/32220 PCTIDK99/00659 ANTI-DANDRUFF COMPOSITION COMPRISING AN ANTIFUNGAL POLYPEPTIDE FIELD OF THE INVENTION s The present invention relates to an anti-dandruff composition comprising an antifungal polypeptide, to the use of an antifun gal polypeptide for the treatment or prophylaxis of dandruff, to a method for the treatment or prophylaxis of dandruff, and to the use of an antifungal polypeptide for the preparation of o10 a composition for the treatment or prophylaxis of dandruff. BACKGROUND OF THE INVENTION Dandruff results from a scalp malfunction but is not considered s15 as being a skin disease and, accordingly, dandruff should be distinguished from the diseases that may mimic it in their early stages. Thus, although dandruff is only of cosmetic concern, a large research effort has been devoted to the field of treating this condition. 20 It is widely accepted that dandruff is mainly caused by the yeast Pityrosporum ovale and, consequently, substances which inhibit the growth of P. ovale might prove useful in the treatment or prophylaxis of dandruff. 25 Active substances which traditionally have been used for treating dandruff include for example various coal tar prepa rations, salicylic acid, selenium sulphide and zinc pyrithione. 30 More recently a novel anti-dandruff shampoo comprising ketoconazole or elubiol has been described in WO 95/27471.

WO00/32220 PCT/DK99/00659 2 However, some of the prior art substances have a very unpleasant smell, while others are very potent substances that may only be applied to the scalp under medical guidance and control. Therefore, there is a need for the development of s substances which are readily produced (e.g. by a micro organism), which do not cause obnoxious smells and which possess no hazardous properties. SUMMARY OF THE INVENTION 10 It has now surprisingly been found that the antifungal polypeptide with the amino acid sequence shown in Fig. 1 efficiently impedes the growth of the yeast P. ovale, even in low concentrations. 15 Accordingly, in a first aspect the present invention relates to an anti-dandruff composition suitable for application to the hair or scalp of a human, comprising an effective amount of an antifungal polypeptide comprising the amino acid sequence shown 20 in Fig. 1, or a variant thereof, said variant being a polypeptide which I) reacts with an antibody reactive with at least one 25 epitope of the polypeptide having the amino acid sequence shown in Fig. 1, or II) has an amino acid sequence which is substantially homologous with the amino acid sequence of the polypeptide 30 shown in Fig. 1.

WO00/32220 PCT/DK99/00659 3 In a second aspect, the present invention relates to the use of an antifungal polypeptide as defined above for the treatment or prophylaxis of dandruff. s In a third aspect, the present invention relates to a method for the treatment or prophylaxis of dandruff, said method comprising contacting hair with an effective amount of an antifungal polypeptide as defined above. i0 Finally, the present invention also relates to the use of an antifungal polypeptide as defined above for the preparation of a composition for the treatment or prophylaxis of dandruff. BRIEF DESCRIPTION OF THE FIGURES 15 Figure 1 shows the full amino acid sequence of the antifungal polypeptide. Figure 2 is a schematic representation of the microtiter plates 20 in which the yeast P. ovale was grown, cf. Example 1. DETAILED DESCRIPTION OF THE INVENTION The antifungal polypeptide and variants thereof 25 In the present context, the three-letter code of the amino acids has been used in its conventional meaning. Unless indicated explicitly, the amino acids mentioned herein are L amino acids. 30 The term "antifungal polypeptide" as used herein is intended to comprise the linear as well as the active folded structures of WO00/32220 PCT/DK99/00659 4 the polypeptide, and may, where appropriate, be used interchangeably with the term "antifungal protein". The term "variant" as used in connection with the antifungal s polypeptide is intended to indicate a polypeptide which is derived from the polypeptide having the amino acid sequence shown in Fig. 1, or a naturally occurring variant. Typically, the variant differs from the native antifungal polypeptide by one or more amino acid residues, which may have been added or l0 deleted from either or both of the N-terminal or C-terminal end of the polypeptide, inserted or deleted at one or more sites within the amino acid sequence of the polypeptide, or substituted with one or more amino acid residues within, or at either or both ends of the amino acid sequence of the s15 polypeptide. Furthermore, the variant of the invention has one or both of the characteristic properties I) and II) mentioned above. 20 Property I), i.e. the reactivity of the variant of the invention with an antibody raised against or reactive with at least one epitope of the polypeptide having the amino acid sequence shown in Fig. 1 below, may be determined using an antibody preparation produced as described under the heading " 25 Production of antibodies against the AFPP" in the Materials and Methods section below. The antibody reactivity may be determined using assays known in the art, examples of which are Western Blotting or radial immunodiffusion assay, e.g. as described by Hudson et al., 1989. 30 The homology referred to above of the AFPP is determined as the degree of identity between two protein sequences indicating a WO00/32220 PCT/DK99/00659 5 derivation of the first sequence from the second. The homology may suitably be determined by means of computer programs known in the art such as GAP provided in the GCG program package (Program Manual for the Wisconsin Package, Version 8, August 5 1994, Genetics Computer Group, 575 Science Drive, Madison, Wisconsin, USA 53711) (Needleman, S.B. and Wunsch, C.D., (1970), Journal of Molecular Biology, 48, p. 443-453). Using Gap with the following settings for polypeptide sequence comparison: Gap creation penalty of 3.0 and Gap extension i0 penalty of 0.1, the mature part of a polypeptide encoded by an analogous DNA sequence of the invention exhibits a degree of identity preferably of at least about 60%, such as at least about 70%, at least about 80%, at least about 90%, at least about 95%, more preferably at least about 97%, and most 15 preferably at least about 99% with the mature part of the amino acid sequence shown in figure 1. Preferably, the AFPP comprises the amino acid sequences of figure 1; or allelic variants thereof; or fragments thereof 20 that has AFPP activity. A fragment of AFPP is a polypeptide which have one or more amino acids seleted from the amino and/or carboxyl terminus of this amino acid sequence. An allelic variant denotes any of two 25 or more alternative forms of a gene occupying the same chromosomal locus. Allelic variation arises naturally through mutation, and may result in polymorphism within populations. Gene mutations can be silent (no change in the encoded polypeptide) or may encode polypeptides having altered amino 30 acid sequences. An allelic variant of a polypeptide is a polypeptide encoded by an allelic variant of a gene.

WO00/32220 PCT/DK99/00659 6 The amino acid sequences of homologous AFPP may differ from the amino acid sequence of figure 1 by an insertion or deletion of one or more amino acid residues and/or the substitution of one or more amino acid residues by different amino acid residues. s Preferably, amino acid changes are of a minor nature, that is conservative amino acid substitutions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of one to about 30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino i0 terminal methionine residue; a small linker peptide of up to about 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain. s15 The term "effective amount" when used herein is intended to mean an amount of the antifungal polypeptide comprising the amino acid sequence shown in Fig. 1, or a variant thereof, which is sufficient to combat (thereby removing or at least 20 arresting) scaling due to dandruff. Typically, the polypeptide to be used according to the invention is derived from a microorganism. While it is contemplated that the antifungal polypeptide or a variant 25 thereof may be produced by other microorganisms such as bacteria, protozoae and algae, the polypeptide is normally derived from a fungus, in particular a fungus of the genus Aspergillus. 30 As explained in detail in WO 94/01459, the antifungal polypeptide having the amino acid sequence shown in Fig. 1 has been found in several strains of the fungal species A. - WO00/32220 PCT/DK99/00659 7 giganteus, an example of which is the A. giganteus strain deposited with the Centraallbureau voor Schimmelcultures (CBS) under the deposition number CBS 526.65. s However, the antifungal polypeptide, or variants thereof, suitable for the use according to the invention are expected to be derivable from other fungal species, especially other Aspergillus species such as A. pallidus, A. clavatus, A. longivesica, A. rhizopodus and A. clavatonanicus, because of o10 the close relationship which exists between these species and A. giganteus. As explained above the variant of the antifungal polypeptide may be a naturally derived variant, i.e. a polypeptide isolated 15is from any of the fungal species listed above, or may be a synthetically produced variant constructed on the basis of the knowledge of the amino acid sequence of the antifungal polypeptide. 20 As indicated previously, other variants of the antifungal polypeptide may also be useful for the purposes of the present invention. Therefore, it is contemplated that interesting variants of the polypeptide shown in Fig. 1, which will also be useful in the treatment or prophylaxis of dandruff, may be 25 identified on the basis of an analysis of the conformational structure and the active site of the antifungal polypeptide shown in Fig. 1 using techniques known in the art, examples of which are NMR (e.g. as described in Protein Engineering, Editors Oxender, D.L. and Fox, C.F., Alan R. Liss, Inc. New 30 York (1987), X-ray diffraction, computer modelling etc. When one or more interesting modifications of the amino acid sequ ence of the antifungal polypeptide have been identified, the WO00/32220 PCT/DK99/00659 8 corresponding variants may be prepared by suitably modifying a nucleotide sequence encoding the antifungal polypeptide. Previously, Nakaya et al. (1990) disclosed the amino acid 5 sequence of an A. giganteus antifungal polypeptide. Wnendt et. al. (1990) described the corresponding cDNA sequence, and in WO 91/19738 the use of this cDNA sequence in the construction of trangenic plants capable of producing the polypeptide was described. The antifungal polypeptide used in the examples i0 given herein (i.e. the antifungal polypeptide having the amino acid sequence shown in Fig. 1) differs from the antifungal polypeptide disclosed in WO 91/19738 as follows: Asn-4 has been replaced with Pro, Ala-24 has been replaced with 15 Gly, Lys-32 has been replaced with Arg, Phe-42 has been replaced with Leu and Tyr-50 has been replaced with His. Thus, a specific example of an interesting variant of the polypeptide shown in Fig. 1 for use in the treatment or 20 prophylaxis of dandruff is an antifungal polypeptide which comprises, and preferably consists of, the amino acid sequence shown in Fig. 1, in which Pro in position 4 has been substituted with Asn, Gly in position 24 has been substituted with Ala, Arg in position 32 has been substituted with Lys, Leu 25 in position 42 has been substituted with Phe, and/or His in position 50 has been substituted with Tyr. Another interesting variant has been disclosed in WO 94/01459. The amino acid sequence disclosed in WO 94/01459 differs from o30 the amino acid sequence shown in Fig. 1 in the following way: WO00/32220 PCT/DK99/00659 9 Pro-4 has been replaced with Asp, Gly-24 has been replaced with Ala, Arg-32 has been replaced with Val, Leu-42 has been replaced with Phe and His-50 has been replaced with Tyr. s Therefore, another specific example of an interesting variant of the polypeptide shown in Fig. 1 for use in the treatment or prophylaxis of dandruff is an antifungal polypeptide which comprises, and preferably consists of, the amino acid sequence shown in Fig. 1, in which Pro in position 4 has been 10 substituted with Asp, Gly in position 24 has been substituted with Ala, Arg in position 32 has been substituted with Val, Leu in position 42 has been substituted with Phe, and/or His in position 50 has been substituted with Tyr. 15is It is contemplated, however, that other variants than those mentioned above, may prove useful in the treatment or prophylaxis of dandruff. Thus, the use according to the invention of such variants, wherein one or more of the amino acid residues in position 4, 24, 32, 42 and 50 of the 20 antifungal polypeptide shown in Fig. 1 have been substituted with another naturally occurring amino acid residue is also within the scope of the present invention. The antifungal polypeptide shown in Fig. 1, as well as variants 25 thereof, may be prepared by methods known in the art. A detailed description of the preparation of the polypeptide shown in Fig. 1 is given in WO 94/01459 Anti-dandruff compositions 30 Although the compositions described herein will, for the sake of simplicity, generally be referred to as "shampoo compositions" it will be understood by persons skilled in the WO00/32220 PCT/DK99/00659 10 art that the antifungal polypeptide may also be incorporated into any other composition suitable for application to the scalp or hair. Therefore, such non-shampoo compositions comprising the antifungal polypeptide are also within the scope 5 of the present invention. Examples of such other compositions are solutions, suspensions, emulsions, gels, foams, creams, etc. Thus, while a shampoo is the presently preferred composition for applying the antifungal polypeptide of the invention, it is also contemplated that the antifungal 10 polypeptide may be applied by other means, e.g. formulated into a hair gel or mousse, a hair tonic, a hair spray, a hair conditioner, a hair dressing, etc. Shampoo compositions may be adapted to oily, dry or normal hair 15 and may be prepared in a manner well-known to the person skilled in the art, e.g. such as described in "Woodruff's ingredients & formulary handbook", 1997, Miller Freeman. Similarly, a hair gel or mousse, a hair tonic, a hair spray, a hair conditioner, etc. may also be prepared using ingredients 20 and methods known in the art for the preparation of such compositions adapted to be applied to the hair or scalp. It will be clear to persons skilled in the art, however, that anti-dandruff compositions according to the invention should not be produced using ingredients or methods (e.g. excessively 25 high temperatures) that would tend to inactivate the antifungal polypeptide. The active ingredient, i.e. the antifungal polylpeptide comprising the amino acid sequence shown in Fig. 1, or a 30 variant thereof, is employed in the shampoo composition in an amount which is effective for treatment or prophylaxis of dandruff.

WO00/32220 PCT/DK99/00659 11 The shampoo composition of the present invention will typically contain the antifungal polypeptide in an amount from about 10 7 to about 10 percent by weight calculated on the total weight of 5 the shampoo composition. Preferably the amount of antifungal polypeptide is in the range from about 5x10 - 6 to about 5% such as in any of the below sub-ranges: about 5x10 6 to about 0.5%; about 5x10 - to about 0.1%; about 5x10 -6 to about 10-%; about 10 - to about 10-%; about 10 4 to about 10-%; about 10' to about 10 0.01%; about 0.01 to about 0.1%; about 0.1% to about 1.0%; and about 1.0% to about 5.0%. Shampoo compositions according to the present invention may contain one or more surfactants, which are employed principally 15 as cleansing agent. Selection of suitable surfactants is a matter of common general knowledge for the person skilled in the art. Usually anionic surfactants are employed in shampoo compositions. Examples of such anionic surfactants are alkali metal, ammonium or hydroxyalkylamine salts of alkyl sulphates, 20 alkyl benzene sulphonates, alkyl sulphones, a-alkenyl sulphonates, polyoxyethylenealkylphenyl sulphonates and polyoxyethylenealkylphenyl sulphates. Mixtures of surfactants may also be used. 25 A specific example of a suitable surfactant which may be included in the shampoo composition according to the invention is sodium laureth sulphate, which has the formula

Cocoyl sarcosine is the coconut oil fatty acid amide of sarcosine (N-methylglycine) and coconut fatty acid is a mixture of myristic acid, lauric acid, palmitic acid and stearic acid. 5 Other specific examples of suitable surfactants which may be incorporated in the shampoo composition of the present invention include sodium C 14 , C1. and C16 olefin sulphonates, sodium lauryl sulphate, cocamidopropylamine oxide, lauramido 10 diethanolamine (lauramido DEA), cocamidopropyl betaine, disodium oleamido MIPA sulfosuccinate, disodium cocamido MIPA sulfosuccinate, disodium laureth sulfosuccinate, cocoaamphocarboxy-glycinate and disodium MEA sulfosuccinate. s15 Another interesting class of surfactants which may be incorporated in the composition of the present invention are sugar surfactants. Examples of surfactants in the form of sugar surfactants include (a) alkyl- and/or alkenyloligoglycosides and/or (b) fatty acid-N-alkylpolyhydroxyalkylamides. 20 The alkyl- and/or alkenyloligoglycoside (a) may have the formula (I): R -O - [G]P (I) 25 in which R1 = a C 4 22 alkyl and/or alkenyl group, G = a sugar residue with 5 or 6 carbon atoms, and p = 1-10.

WO00/32220 PCT/DK99/00659 15 The shampoo composition of the present invention may also contain one or more viscosity enhancing agents in order to confer the shampoo a suitable "thickness". Examples of such viscosity enhancing agents are Carbopol 1342 and cellulose s derivatives such as hydroxypropyl methylcellulose, hydroxyethyl cellulose, carboxymethyl cellulose, and the like. Addition of small amounts (usually from 0.2 to 5.0% by weight) of NaCl may also be used in order to control the viscosity of the final shampoo composition. 10 In addition, the compositions of the present invention may also include one or more preservatives such as tetrasodium EDTA (the tetrasodium salt of ethylenediamine tetraacetic acid), quaternium-15 (l-(3-chloroallyl)-3,5,7-triaza-l-azonia s15 adamantane chloride), Kathon CG biocide (a mixture of 5-chloro 2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3 one), paraben, methylparaben, benzyl alcohol, and the like. As will be understood by the person skilled in the art the 20 compositions of the present invention may also contain other accessory agents such as perfume, colouring agents, opacifiers, conditioning agents such as polyquaternium-7 (which is the polymeric quaternary ammonium salt of acrylamide and dimethyl diallyl ammonium chloride), pearlizing agents such as ethylene 25 glycol distearate and ethylene glycol monostearate, antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), and/or pH adjusting agents such as, for example, citric acid, phosphoric acid, sodium hydroxide, and the like. 30 Furthermore, the compositions of the present may also contain one or more therapeutically active components in addition to WO00/32220 PCT/DK99/00659 16 the antifungal polypeptide. Examples of such therapeutically active components are piroctone (an antiseborrheic agent whose chemical name is l-hydroxy-4-methyl-6-(2,4,4-trimethylpentyl) 2(lH)-pyridinone), ketoconazole and elubiol. 5 In general, the components of the shampoo composition are employed in conventional amounts, for example: i) 10-65% surfactants, 10 ii) 1-10% foaming agents, iii) 0.1-2% viscosity enhancing agents, iv) preservatives and/or antioxidants sufficient to retard degradation of the shampoo composition, thereby providing an adequate shell life, is v) acids, bases or buffers to yield a pH in the desired range (typically from 4 to 10) vi) water qs ad 100% Below, a number of specific examples of various shampoo 20 compositions comprising the antifungal polypeptide defined above is given (in the examples the antifungal polypeptide as defined above is abbreviated AFPP): Shampoo Composition I ("All-Purpose Shampoo for Normal Hair" ) 25 A.

In brief, the antifungal polypeptide was prepared as follows: A. giganteus strains 10 The A. giganteus strain deposited with the Centraalbureau voor Schimmelculturen (CBS) under the accession number CBS 526.65 was used for the experiments. Cultivation of an A. qiganteus strain producing the AFPP 15 Cultivation on agar slants was carried out using an agar medium prepared from 39 g of Potato Dextrose Agar (from Difco) and distilled water up to 1000 ml. The agar slants were inoculated with the A. giganteus strain and grown for one week at 26 0 C. 20 Submerged cultivation A 500 ml Erlenmeyer flask containing 100 ml of AMC substrate (15 g meat extract, 20 g Peptone, 20 g corn starch, 5 g NaCI, 1 ml Pluronic, 1 litre H 2 0) was inoculated with 5 ml of a spore suspension containing 10' spores/ml prepared from an agar slant 25 culture of A. giganteus obtained as described above containing 10g spores per ml. The flask was shaken at 220 rpm at 30 0 C for 3 days, after which the AFPP could be recovered. Isolation, purification and amino acid sequence determination 30 of the AFPP The fermentation broth obtained as described above was sub jected to centrifugation, the mycelium was suspended in Tris- WO 00/32220 PCT/DK99/00659 38 buffered saline at pH 7 and then subjected to a second cen trifugation. The supernatants from the two centrifugations were combined and subjected to sterile filtration. The pH of the resulting supernatant preparation was adjusted to between 6.5 s and 9 and the supernatant preparation was applied to a cation exchange resin (S Sepharose Fast Flow) which prior to application was equilibrated with a phosphate buffer at pH 6.5. Elution of active fractions from this resin was accomplished by the application of a buffer with a high ionic strength such as i0 a buffer comprising 20 mM phosphate, 1.5 mM NaCl, pH 6.5. If necessary, the procedure was repeated after dilution with or dialysis against a buffer with ionic strength below or near that of 10 mM phosphate at pH 6.0. Elution from this second step was, if necessary, carried out as a gradient elution. The s15 purity of the active fractions was assessed by HPLC. The combined active fractions were subjected to sterile filtration on a 0.22 Am filter (Millipore) prior to testing of the antifungal properties against P. ovale. 20 The purified AFPP was S-carboxymethylated using the method described by Nakaya et al. 1990 and de-salted using reverse phase HPLC. The S-carboxymethylated AFPP was subjected to N terminal amino acid sequence determination on an Applied Bio 25 systems 473A sequencer operated in accordance with the manufacturer's instructions. Extinction coefficient The extinction coefficient of the AFPP was estimated from the 30 amino acid sequence shown in Fig. 1 using the formula 6'"(280 nm)=5690- (No. Trp)+1280- (No. Tyr)+120-(No. Cys) WO00/32220 PCT/DK99/00659 39 molecular mass (Gill & von Hippel, 1989), where (No. Trp), (No. Tyr) and (No. Cys) are the number of Trp, Tyr and Cys residues in the amino 5 acid sequence. Based on this formula the extinction coefficient at 280 nm has been calculated to 1.3. All polypeptide determinations are based on OD 280 measurements using this calculated extinction co o10 efficient. Production of antibodies against the AFPP The AFPP produced and purified as described above was diluted to a concentration of 25-250 Ag/ml in phosphate-buffered 15 saline, pH 6.5-8. Rabbits were immunised with the purified polypeptide in Freund's complete adjuvant by use of an immunisation scheme essentially according to the standard procedures described by Hudson et al., 1989. Serum may be collected and tested for polyspecific antibodies against the 20 AFPP in a single radial immunodiffusion assay or a western blot assay using the purified AFPP obtained as described above as an antigen. The assays may be carried out in accordance with standard procedures, e.g. as described by Hudson et al., 1989. The antibodies may be purified by standard methods such as 25 standard immunoadsorbent techniques using the purified AFPP immobilised to a carrier, e.g. as described by Hudson et al., 1989. Determination of antibody reactivity of a variant of the AFPP 30 of the invention Reactivity of a variant of the AFPP with an antibody or an antibody-containing serum obtained as described above may be WO00/32220 PCT/DK99/00659 40 determined in single radial immunodiffusion or western blotting performed essentially as described by Hudson et al., 1989. EXAMPLE 1 5 Inhibition of the yeast P. ovale P. ovale was grown in microtiter plates in a medium recommended by American Type Culture Collection at 37 0 C. The medium contains 30 g Sabouraud's glucose broth, 5 g yeast extract and lo 2 ml olive oil pr. litre. A standard solution comprising the AFPP was prepared by dissolving the AFPP in 10 mM phosphate buffer, pH 7.5. 15 As illustrated in Fig. 2, each microtiter plate contained 4 identical lanes, each lane having: One well containing medium only (200 ml) and 50 ml 10 mM phosphate buffer, pH 7.5 (included as a control in order 20 to test the sterility of the medium. The phosphate buffer was included in order to ensure identical experimental conditions compared to the wells inoculated with P. ovale). 25 - One well identical to the above-mentioned well except being inoculated with P. ovale. - One well inoculated with P. ovale and containing AFPP in a concentration of 0.005 OD 280 (about 5 mg AFPP/litre) 30 One well inoculated with P. ovale and containing AFPP in a concentration of 0.027 OD 280

.

WO00/32220 PCT/DK99/00659 41 One well inoculated with P. ovale and containing AFPP in a concentration of 0.068 OD 280 . 5 - One well inoculated with P. ovale and containing AFPP in a concentration of 0.136 OD 280 . The growth of P. ovale was followed as a function of time. The yeast did not grow uniformly, but rather in large 10 agglomerations. This fact, and the presence of olive oil, made it impossible to measure the growth by spectroscopic means. Therefore, the cells were re-suspended and 10 l was plated on the same medium containing agar. Determination of the approximate growth in microtiter plates and on solid medium s15 plates gave the same results (see Table 1). The results shown in Table 1 are the average growth in the four lanes. The growth was dependent on the size of the colony used for inoculation. The larger the colony, the faster the growth on 20 the plates. In the present example the medium was inoculated with only a small colony. As it appears from Table 1 below, this gave rise to an extended period of growth. However, the results shown in Table 1 were the same as if the medium was inoculated with a larger colony, except that the growth period 25 was shortened.

The fact that even a very low concentration of AFPP (for example about 5 mg/litre) inhibits the growth of P. ovale renders the AFPP suitable for use in the treatment or prophylaxis of dandruff. 15 WO00/32220 PCT/DK99/00659 43 REFERENCES CITED IN THE SPECIFICATION Gill & von Hippel, Anal.
