摘要:THIS INVENTION RELATES TO NOVEL 3-MONO(ALKYL CARBONATE) AND 2,3-BIS(ALKYL CARBONATE) ESTERS OF 7-HALOGENATED LINCOMYCIN COMPOUNDS OF THE FORMULA 2-(R-S-),3-(R4-O-),4-(R3-O-),5-(HO-),6-((1-R2,4-R1- PYRROLIDIN-2-YL)-CO-NH-CH(-CH(-X)-CH3)-)TETRAHYDROPYRAN WHEREIN R IS ALKYL OF FROM 1 THROUGH 6 CARBON ATOMS; R1 IS ALKYL OF FROM 1 THROUGH 8 CARBON ATOMS, CYCLOALKYL OF FROM 3 THROUGH 8 CARBON ATOMS, OR ARALKYL OF UP TO 12 CARBON ATOMS; R2 IS HYDROGEN OR ALKYL OF FROM 1 THROUGH 8 CARBON ATOMS; X IS CHLORINE, BROMINE OR IODINE; R3 IS CNH(2N+1)-OOC- WHEREIN N IS AN INTEGER FROM 1 THROUGH 20 AND R4 IS R3 OR HYDROGEN; THEIR ACID ADDITION SALTS; AND NOVEL SYNTHESIS PROCESSES. THESE ALKYL CARBONATE ESTERS OF LINCOMYCIN COMPOUNDS HAVE ANTIBIOTIC ACTIVITY. FOR EXAMPLE, THE 3-MONO(ALKYL CARBONATE) ESTERS CAN BE USED TO INHIBIT THE GROWTH OF STAPHYLOCOCCUS AUREUS, STREPTOCOCCUS HEMOLYTICUS AND STREPTOCOCCUS FAECALIS ON MEDIAL AND DENTAL EQUIPMENT CONTAMINATED WITH THESE BACTERIA. THE 2,3-BIS(HEXLY CARBONATE) ESTER OF 7-DEOXY-7(S)-CHLOROLINCOMYCIN IS ADVANTAGEOUS FOR ORAL ADMINISTRATION AS AN ANTIBIOTIC IN THAT IT LACKS THE BITTER TASTE OF THE UNESTERIFIED COMPOUND.
