Appl. No.:

09/735056

Inventors:

Leonard Katz - Wheeling IL, US
Diane Stassi - Highland Park IL, US
Richard Summers - Nashotah WI, US
Xiaoan Ruan - Lake Bluff IL, US
Stephan Kakavas - Buffalo Grove IL, US

International Classification:

A61K031/7048
C07H017/08

US Classification:

514/028000, 536/007400, 536/007100

Abstract:

The invention provides novel erythromycin derivatives in which methyl groups on the macrolactone ring have been substituted with —H, -Et, and/or —OH. The invention also provides reagents such as isolated polynucleotides, vectors comprising the polynucleotides and host cells transformed with the vectors for making the novel compounds. Methods for making the compounds utilizing genetic engineering techniques are also disclosed.

C07H 1708

US Classification:

435 4

Abstract:

The invention provides novel erythromycin derivatives in which methyl groups on the macrolactone ring have been substituted with --H, -Et, and/or --OH and the ethyl side-chain has been substituted with hydroxymethyl or dihydroxycyclohexylmethyl side-chains. The invention also provides reagents such as isolated polynucleotides, vectors comprising the polynucleotides and host cells transformed with the vectors for making the novel compounds. Methods for making the compounds utilizing genetic engineering techniques are also disclosed.
