- Synthesis of bioactive substituted pyrazolylbenzothiazinones
-
Abstract Pyrazolylbenzothiazinones have been synthesized in good yields by the reaction of 2-hydrazinocarbonymethyl-3,4-dihydro-2H-1,4-benzothiazin-3-ones with β-diketone in the presence of ethanol. The structures of synthesized pyrazolylbenzothiazinones were confirmed on the basis of their analytical and spectral data. The antimicrobial activities of the synthesized compounds have also been included.

- Synthesis and biological evaluation of novel benzothiazole clubbed fluoroquinolone derivatives
-
In the present investigation, synthesis and anti-bacterial, analgesic and anthelmintic evaluation of a novel series of fluoroquinolone derivatives clubbed with benzothiazole moeity has been described. The synthesized compounds were characterised by spectral analysis (IR and H NMR). Preliminary results indicated that the most of the synthesized compounds demonstrated good activities against gram negative and gram positive bacterial strains. Compounds 5a, 5b, 5f and 5k demonstrated potent anti-bacterial activities. Compound 5a exhibited most potent anti-bacterial activity with MIC values of 04, 03, 08 and 15 μg/ mL against B. subtilis, S. aureus, E. coli and P. aeruginosa. Analogs 5a, 5c, 5g and 5h showed promising anthelmintic activity against Eisemia foetida in a low concentration as compared to standard drug piperazine citrate with mean paralysis time ranging 22.60 ± 2.46 to 31.60 ± 3.07 min. All synthesized compounds depicted good in vivo analgesic activity with compound 5a exhibiting the most potent activity of 55.19% inhibition of writhing in comparison to the standard drug.

- Solid phase synthesis of 2-aminobenzothiazoles
-
A traceless solid supported protocol for the synthesis of 2-aminobenzothiazoles is described, employing resin-bound acyl-isothiocyanate and a series of anilines. Cyclization of the resulting N-acyl, N′-phenyl-thioureas generates the 2-aminobenzothiazole scaffold, which can be further elaborated prior to hydrazine-mediated cleavage of the final products from the carboxy-polystyrene resin. A small, focused library of 2-aminobenzothiazoles was prepared.
