Definitions
- the invention relates to sulfonamide prodrugs of the general formula (I)
- X is a heteroaromatic, a process for the preparation of these prodrugs, pharmaceutical compositions containing these compounds and their use for the preparation of orally available drugs.
- WO 01/91797 discloses steroidal compounds which are bound to erythrocytes via a group - SO 2 NR 1 R 2 and accumulate there.
- concentration ratio of the compounds between erythrocytes and plasma is 10- 1000: 1, preferably 30-1000: 1, so that one can speak of a deposit formation in the erythrocytes. Strong binding of the compounds to the erythrocytes avoids metabolism during liver passage. Disadvantageously, despite a reduced metabolization with the indicated dosages no therapeutically relevant drug levels are given. Reasons for this are to be found in an excessive binding to erythrocytes, an enzyme-induced cleavage and in low solubilities.
- heterocyclic sulfonamide prodrugs of the general formula (I) in which a sulfamoyl radical is bonded to the drug to be released via a heteroaromatic spacer X by means of a carboxylic ester bond, in which
- X is an unsubstituted or substituted heteroaromatic radical or an alkyl radical
- Drug a pharmaceutical agent which can form a carboxylic acid ester via an OH group, such as steroids, antimalarials, nucleosides, isoflavonoids, which may optionally be substituted.
- the sulfonamide prodrugs according to the invention with heteroaromatic linker X bind to erythrocytes, are readily soluble in water and are hydrolytically cleaved without the involvement of enzymes.
- a heteroaromatic radical means, for example, thiophene, pyridine, pyrrole, furan or else thiophene, pyridine, pyrrole or furan substituted by C 1-4 -alkyl or halogen.
- Substituted heteroaromatics include 2-bromothiophene, 2-ethylthiophene, N-methylpyrrole and 2-bromopyridine.
- Ci -4 alkyl is methyl, ethyl, propyl, butyl or isopropyl group.
- halogen atom is understood to mean a fluorine, chlorine, bromine or iodine atom, preferably a fluorine, chlorine, bromine atom.
- alkyl heteroaromatic means a heteroaromatic bonded to the ester function via a C 1 -C 4 alkyl radical.
- Heteroaromatics means the groups named heteroaromatic radical.
- D 3 -alkyl radical denotes a methylene, ethylene or propylene bridge.
- Preferred heteroaromatics are pyridine and thiophene. Preferred compounds are listed below:
- the therapeutically relevant drug compound is released by hydrolysis.
- the sulfamoyl prodrugs of the general formula (I) according to the invention surprisingly inhibit the carbonic anhydrase II. From this an accumulation of the prodrugs according to the invention in the erythrocytes can be deduced.
- the SO 2 -NH 2 group of the substances according to the invention can lead to an accumulation in erythrocytes by binding to carbonic anhydrases.
- Freshly obtained, heparinized blood of a rat is mixed with a defined amount of active ingredient.
- the active substance concentration in the plasma obtained therefrom is measured against a calibration curve from spiked (with known active ingredient concentration) plasma.
- the blood-plasma ratio is calculated from the measured concentration and the theoretical concentration.
- the concentration ratios of the compounds according to the invention between erythrocytes and plasma are not in a range of 10-1000: 1, but in the range ⁇ 10: 1. This has proven to be a major disadvantage for achieving therapy-relevant active ingredient levels.
- suitable linkers it is possible to set the optimal blood / plasma ratio for a prodrug compound.
- the compounds of the general formula (I) can be used in the case where "Drug "a steroid such as androgen or estrogen is used in hormone replacement therapy (HRT) in women and men or in the treatment of hormonal disorders in men (prostate, breast cancer, hypogonadism) and women (endometriosis, breast cancer) become.
- HRT hormone replacement therapy
- the compounds of the general formula (I) according to the invention in which "drug” is, for example, an androgen or estrogen, can be used for fertility control in men or women
- drug is, for example, an androgen or estrogen
- further drugs mentioned for “drugs” such as quinine, chinchonidine, hydroxychloroquine, Primaquine or mefloquine concerns the treatment of malaria.
- drug is a cortisol derivative
- drug is a nucleoside (zidovudine, brivudine, indinavir, nelfinavir) and can be used to treat viral diseases (herpes, HIV).
- the invention also provides the pharmaceutical compositions comprising the compounds of the general formula (I) according to the invention and optionally other active compounds, for example progestagens (norethisterone, dienogest, drospirenone, levonorgestrel), antigestagens (mifepristone, onapristone) and / or progesterone receptor modulators (mesoprogestins such as asoprisnil).
- active compounds for example progestagens (norethisterone, dienogest, drospirenone, levonorgestrel), antigestagens (mifepristone, onapristone) and / or progesterone receptor modulators (mesoprogestins such as asoprisnil).
- compositions and medicaments are preferably administered orally.
- pharmaceutical compositions and medicaments are preferably administered orally.
- conventional carriers and / or diluents they contain at least one compound of the general formula I.
- the prodrugs according to the invention can be administered orally.
- compositions of the invention are prepared in a known manner with the usual solid or liquid carriers or diluents and the commonly used pharmaceutical excipients according to the desired mode of administration with a suitable dosage.
- the preferred preparations consist in one Dosage form suitable for oral administration.
- dosage forms are, for example, tablets, coated tablets, dragees, capsules, pills, powders, solutions or suspensions or depot forms.
- Corresponding tablets for example, by mixing the active ingredient with known excipients, for example inert diluents such as dextrose, sugar, sorbitol, mannitol, polyvinylpyrrolidone, disintegrants such as corn starch or alginic acid, binders such as starch or gelatin, lubricants such as magnesium stearate or talc and / or agents to achieve Depot effect such as carboxyl polymethylene, carboxymethyl cellulose, cellulose acetate phthalate or polyvinyl acetate, are obtained.
- excipients for example inert diluents such as dextrose, sugar, sorbitol, mannitol, polyvinylpyrrolidone, disintegrants such as corn starch or alginic acid, binders such as starch or gelatin, lubricants such as magnesium stearate or talc and / or agents to achieve Depot effect such as carboxyl polymethylene, carb
- Coated tablets can accordingly be prepared by coating cores produced analogously to the tablets with agents customarily used in tablet coatings, for example polyvinylpyrrolidone or shellac, gum arabic, talc, titanium oxide or sugar.
- the dragee wrapper can also consist of several layers, wherein the auxiliaries mentioned above in the case of the tablets can be used.
- Solutions or suspensions with the compounds of general formula I according to the invention may additionally taste-improving agents such as saccharin, cyclamate or sugar and z.
- B. flavorings such as vanillin or orange extract. They may also contain suspending aids such as sodium carboxymethylcellulose or preservatives such as p-hydroxybenzoates.
