Definitions
- This invention is concerned with compounds useful for the prevention or suppression of human malodour, in particular human axillary malodour.
- Fatty acids in particular short chain, branched fatty acids are known to play a role in axillary malodour, and are particularly foul smelling components of stale sweat.
- PCT/CH02/00262 the applicant has disclosed an enzyme that mediates in a process of transforming odourless compounds found in sweat into these malodorous fatty acids.
- this co-pending application there is also disclosed a broad class of compounds having activity as inhibitors of the enzyme.
- R is a substituted alkyl, benzyl or allyl residue selected from the group consisting of a) nonyl; b) 4,4,4-trifluoro-propyl; c) 2-methyl-4-phenyl-butyl; d) 4-trifluoromethyl-phenyl; e) pentafluorophenyl; f) 4-fluoro-phenyl; g) naphthalene-2-yl; h) biphenyl-2-yl; i) 5 ,5 ,7, 8, 8-pentamethyl-5 ,6,7, 8-tetrahydro-naphthalene-2-yl; k) 5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-naphthalen-2-yl;
- Compounds of the formula (I) contain chiral atoms and as such they can exist as isomeric mixtures or they may exist as pure stereoisomers. Most preferred are compounds have an S-configuration on the carbon atom in the position alpha to the carboxyl group.
- compounds of the present invention may interact with an enzyme thereby to reduce the enzyme's ability to cleave compounds in sweat leading to release of malodorous acids from odourless fresh sweat.
- That enzyme described in the afore-mentioned co-pending application, was isolated from the bacteria of the genus Corynebacteria that can be found colonising the axilla, in particular certain Corynebacteria sp., more particularly Corynebacterium striatum Ax 20 which has been submitted on the 26, April 2001 to the International Depository Authority DSMZ- Deutsche Sammlung von Mikrooganismen und Zellkulturen GmbH, D-38124 Braunschweig. The Accession Number provided by the International Depository Authority is DSM 14267.
- the enzyme was found to occur intracellularly and can be released from the cells by mechanical disruption of the cell envelope.
- it may be isolated from cellular extracts obtained from wild-type bacterial strains, especially from strains of Corynebacteria isolated from the human axilla, in particular Corynebacterium striatum Ax 20.
- it may be produced by recombinant means which are well known to persons skilled in the art.
- the amino acid sequence of this enzyme is set forth in SEQ ID No. 1 and a nucleic acid sequence encoding for this enzyme is set forth in SEQ ID No. 2, both of which sequences are shown below.
- Compounds of the present invention display inhibition of the enzyme at concentrations of about 1 to 500,nanomolar more particularly from 5 nanomolar 500 nanomolar concentration in vitro, e.g. from 9 to 150 nanomolar. Furthermore, having regard to the lipophilicity of the residue R, the compounds are adapted to penetrate the cell walls of the enzyme-producing bacteria, as such, they are therapeutically.
- the nature of the residue R appears to influence the ability of compounds to penetrate the cellular walls of different bacteria colonising the axilla and which are implicated in malodour production.
- other strains of Corynebacteria for example Corynebacterium bovis and Corynebacterium je ⁇ keium
- bacteria of the genus Staphylococci found in the microflora of the axilla also produce related enzymes that themselves mediate in biochemical reactions wherein L-glutamine derivatives are cleaved atN ⁇ .
- the compounds of the present invention may interfere in cellular processes of a wide variety of bacterial strains thereby resulting in the suppression or prevention of malodour from these sources.
- the in vitro activity of the compounds as inhibitors may be measured in terms of either their IC 50 values or their Ki values, both of which measures are well known to the person skilled in the art.
- the IC50 value provides the concentration of an inhibitor needed to reduce enzyme velocity by half at a given substrate concentration. This value is dependent on the affinity of the substrate for the enzyme which is reflected in the value K m of the substrate.
- the Ki value may be determined for a given substrate and a given substrate concentration by measuring IC 50 and then calculating according to the following formula
- the uptake of the compounds in bacterial cells and the inhibition of the enzyme contained therein may be measured using an assay based on stationary-phase living cells.
- cells may be incubated along with inhibitory compound or compounds, and the substrate (i.e. the material found in sweat, which when cleaved by the enzyme forms the malodorous acids), and the release of acids may be measured at various inhibitor concentrations.
- the substrate i.e. the material found in sweat, which when cleaved by the enzyme forms the malodorous acids
- the release of acids may be measured at various inhibitor concentrations.
