Patent ID: 8822414

Claim:
A compound of formula (I) including its tautomeric form, its steroisomer, and its pharmaceutically acceptable salt. wherein ‘A’ represents an optionally substituted single or fused group selected from arly, heterocyclyl and cycloalky groups; wherein ‘Y’ represents either (i) a bond or (ii) a moiety selected from a substituted or unsubstituted, linear or branched (C 1 -C 6 )alkyl group, a substituted or unsubstituted, linear or branched (C 2 -C 6 )alkenyl group, and a group represented by ‘—U(CH 2 ) m -’ wherein U represents a moiety selected from O, S(O) o , and NR 4 and ‘m’ represents integers from 2 to 4, and wherein ‘o’ in S(O) o represents an integer from 0 to 2 and R 4 in NR 4 represents a moiety selected from H and a substituted or unsubstituted linear or branched (C 1 -C 6 )alkyl group; wherein ‘Z’ represents an optionally substituted single or fused group selected from aryl, heterocyclyl and cycloalkyl groups; wherein ‘X’ represents either (i) a bond, or (ii) is selected from O, S(O) o or NR 4 ; wherein ‘o’ in S(O) o represents an integer from 0 to 2 and R 4 in NR 4 is a moiety slected from H and a substituted or unsubstituted linear or branched (C 1 -C 6 alkyl group; wherein ‘W’ represents a moiety selected from a substituted or unsubstituted linear or branched (C 1 -C 6 )alkyl group, and a substituted or unsubstituted linear or branched (C 2 -C 6 ) alkenyl group; wherein R 1 represents hydrogen, or a group selected from a (C 1 -C 6 )alkyl, (C 3 -C 6 )cycloalkyl, alkoxyalkyl, hydroxyalkyl, aminoalkyl, aryl, heterocyclyl, aralkyl, and heterocyclylalkyl, each of which may be optionally substituted; R 2 represents hydrogen, or a group selected from (C 1 -C 6 )alkyl, aryl, heterocyclyl, aralkyl, heterocyclylalkyl, (C 1 -C 6 )alkoxy, hydroxyalkyl, thio(C 1 -C 6 )alkyl, amino, aminoalkyl, and alkylamino, each of which may be optionally substituted; with the proviso that R 1 and R 2 together may optionally form a 4 to 7 membered saturated or partially saturated ring containing from 0-2 additional heteroatoms selected from the group of N, O, and S(O) o , wherein ‘o’ in S(O) o represents an integer from 0 to 2; R 3 at each occurrence independently represents a moiety selected from hydrogen, halogen, an (C 1 -C 3 )alkyl group, a halo(C 1 -C 3 )alkyl group, a (C 1 -C 3 )alkoxy group, a thio(C 1 -C 3 )alkyl group, a sulfenyl derivative, and a sulfonyl derivative; and wherein ‘n’ represents integer from 0-3.
