Patent number: 8865910
Abstract: Invention provides antitubercular compounds selected from propargylated 1,2,3 triazoles of Formula I, wherein, X is sulfur(S) or a sulphone (A), n, m represent independently an integer O or 1, with the provision that when ‘n’ is 1, ‘m’ is 1; R1 is hydrogen; C1-C6 linear or branched alkyl group optionally substituted with aryl group; halogen; or aryl group optionally substituted with —OCH3, halogen, and nitro; R2 and R3 are selected from the group consisting of hydrogen, C1-C6 alkyl optionally substituted with heterocyclic ring of 5 to 6 ring atoms containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, which may be substituted with alkyl, arylalkyl, linear or branched alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, or allyl or propargyl groups consisting of 1 to 6 carbon atoms; Z is C1-C6 alkyl optionally substituted with heterocyclic ring of 1 to 6 ring atoms, containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, which may be substituted with arylalkyl,
