Triazole derivatives useful as anti-tubercular compounds; process for preparation of the triazoles and a method for inhibiting growth ofBCG andH37Ra using the triazoles.

1, 2, 4-triazole derivatives and their anti-microbial activity

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 &#x2014;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, linear or branched alkenyl, substituted alkenyl, alkynyl, substituted alkynyl allyl or propargyl groups consisting of 1 to 6 carbon atoms; with the provision that when &#x2018;m&#x2019; is 1, and &#x2018;n&#x2019; is zero; R1 is selected from the group consisting of hydrogen, halogen; C1-C6 linear or branched alkyl group optionally substituted with aryl group or aryl group optionally substituted with &#x2014;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 selected from the group consisting of halogen, C1-C6 linear or branched alkyl group optionally substituted with heterocyclic ring of 1 to 6 ring atoms, containing one to three hetero atoms selected from oxygen, sulfur, nitrogen, wherein the heterocyclic ring may further be substituted with halogen, alkyl, arylalkyl.

1, 2, 4-triazole derivatives and their anti mycobacterial activity

This invention provides novel substituted 1,4-dioxa-8-azaspiro[4,5]decane compounds of the general formula (1), wherein R1 is selected from phenethyl, 4,6-dimethoxypyrimidin-2-yl and (2-chloro-5-thiazolyl)methyl and R2 is selected from the group consisting of hydroxy, 4-bromo-2-chlorophenoxy, morpholin-4-yl, (2-chloro-5-thiazolyl)methyloxy, benzyloxy, phenylsulfanyl, benzotriazol and 5-chloro-2-fluoroanilino. The present invention also relates to a process for the preparation of novel substituted 1,4-dioxa-8-azaspiro[4,5]decanes of general formula (1). The novel substituted 1,4-dioxa-8-azaspiro[4,5]decane of general formula (1) has fungicidal activity.

Substituted 1, 4-dioxa-8-azaspiro[4,5]decanes useful as fungicides and a process for the preparation thereof
