Studies on synthesis of novel triazole tagged pyrazole fused naphthalene 5-thiazine-5,5-dioxide derivatives, their antimicrobial, and antioxidant activity

A series of novel triazole tagged pyrazole fused naphthalene-5-thiazine-5, 5-dioxide derivatives 8 and 9 were synthesized starting from sodium salt of saccharin 1. The structure of each intermediate and products was established on the basis of spectroscop

Synthesis, molecular docking and antiviral screening of novel N'-substitutedbenzylidene-2-(4-methyl-5,5-dioxido-3-phenylbenzo[e]pyrazolo[4, 3-c][1,2]thiazin-1(4H)-yl)acetohydrazides

N'-Substitutedbenzylidene-2-(4-methyl-5,5-dioxido-3-phenylbenzo[e] pyrazolo[4,3-c][1,2]thiazin-1(4H)-yl)acetohydrazides (7a-u) were synthesized through a multistep reaction. The final compounds were screened for anti-HIV-1 and cytotoxic activities. Among

Novel structural hybrids of pyrazolobenzothiazines with benzimidazoles as cholinesterase inhibitors

Two series of novel pyrazolobenzothiazine-based hybrid compounds were efficiently synthesized starting from saccharin sodium salt. Pyrazolo[4,3-c][1,2]benzothiazine scaffolds were N-arylated by using p-fluorobenzaldehyde, followed by the incorporation of
