Definitions
- the present invention relates to a novel derivative of the antibiotic erythromycin A.
- Erythromycin A is an antibiotic that is widely used as a treatment for infectious diseases caused by gram-positive bacteria, mycoplasmas, and the like. Erythromycin A, however, has the disadvantage that it is degraded by acid in the stomach because it is unstable to acids, and its pharmacokinetics is not constant. Many erythromycin A derivatives have been produced to date to improve such biological or pharmacological properties. For example, a 6-0-methylerythromycin A derivative (U.S. Pat. No. 4,331,803) has improved stability to acids, and has better in vivo antibacterial activity upon oral administration than erythromycin A. It has been reported.
- An object of the present invention is to provide a next-generation macrolide antibiotic having a strong antibacterial activity against not only conventional erythromycin-sensitive bacteria but also erythromycin-resistant bacteria, which have been increasing in recent years. To do that. Disclosure of the invention
- the present inventors have found a compound having antibacterial activity not only against susceptible bacteria but also against resistant bacteria by converting the carboxy group at the 9-position of erythromycin A to a certain substituent.
- the present invention has been completed.
- the present invention provides a compound represented by the formula (I):
- R 1 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.
- R 2 represents a cladino siloxy group, and a formula — OCO-CH 2 -R 4
- R 4 is a phenyl group, a pyridyl group, a quinolyl group, or an alkyl group having 1 to 3 carbon atoms, a cyano group, an amino group, a dimethylamino group, a nitro group, a carbon atom.
- X is an oxygen atom
- n represents an integer of 1 to 5
- R 5 and R 6 are the same or different.
- R 7 is of the formula N—R 9
- R 8 represents a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or an alkanol group having 2 to 7 carbon atoms
- R 9 represents a phenyl group, a benzyl group, a pyridyl group, a pyridylmethyl group.
- R s and R 9 above are the same as) a group represented by or wherein one S0 2 - N-R 9
- Erythromycin A derivative represented by the formula or a pharmaceutically acceptable salt thereof.
- an alkyl group having 1 to 6 carbon atoms means a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, a hexyl group, an isopropyl group, an isopropyl group, a tert-butyl group.
- An isopentyl group, a cyclohexyl group, etc., and an alkanoyl group having 2 to 7 carbon atoms refers to an acetyl group, a propionyl group, an isopropionyl group, a butylyl group, etc., and a halogen atom and Is fluorine, chlorine, bromine Indicates an atom or iodine atom.
- Pharmaceutically acceptable salts refer to salts used in the chemotherapy and prevention of bacterial infections. They include, for example, acetic acid, propionic acid, butyric acid, formic acid, trifluoroacetic acid, maleic acid, tartaric acid, citric acid, stearic acid, succinic acid, ethyl succinic acid, lactobionic acid, dalconic acid, Darcoheptonic acid, benzoic acid, methansulphonic acid, benzoic sulphonic acid, 2-hydroxyethanesulphonic acid, benzenesulphonic acid, para-toluenesulphonic acid, lauryl sulphate, lingoic acid, aspartic acid, glutamin Acids, adipic acid, cystine, N-acetyl cystine, hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, hydroiodic acid, dicotinic acid, oxalic acid, picric acid, thiocyanic acid, pende
- the compound of the present invention can be produced according to Examples described later.
- the compounds of the present invention can be administered orally or parenterally.
- the dosage forms are tablets, capsules, powders, lozenges, ointments, suspensions, suppositories, injections, etc., which can be manufactured by common formulation techniques.
- the dosage is 100-1. OOOmg daily for treatment of adults, which can be administered in 2-3 divided doses a day. This dosage may be adjusted as appropriate according to the age, weight and condition of the patient.
- Example 3 9—Doxo 9—Aminoerythromycin A 9, 11—Cyclic power—Bamate 3 g (4.0 mmol) of 9-deoxo-19-aminoinothromycin A synthesized by the method described in the literature (Tetrahedoron Le 11., p. 29, 1972) was prepared in the same manner as in Example 1 by using a method similar to that of Example 1. To give 0.6 g (yield 193 ⁇ 4) of the title compound.
- the compounds of the present invention have antibacterial activity not only against erythromycin-sensitive bacteria but also against resistant bacteria. Therefore, the compounds of the present invention are useful as antibacterial agents for treating bacterial infections in humans and animals (including farm animals).
