  • The high-performance liquid chromatography method was performed for test method development of related compounds in pharmaceuticals. Using reverse-phase column and gradient elution of 1 % acetonitrile-acetonitrile: H20:triethylamine (70:30:0.5), lansoprazole, 2-hydroxybenzimidazole, 2-mercaptobenzimidazole, lansoprazole sulfone, lansoprazole sulfide could be individually identified and quantitated.

  • The present study is synthesis of derivatives of N'-(4-amino-5-sulfanyl-4H-1,2,4-triazole-3-yl)-2-(1H-benzimidazole-2-ylsulfanyl) acetohydrazide (IV). Antibacterial activity tested against the E. coli and A. Substilis. Biological activities conducted by disc diffusion method. Compound $2MB_1$, $2MB_3$, $2MB_5$ inhibit the appreciable microbial growth while rest of the compound possess the moderate activities. Anti-inflammatory activity tested by reduces local edema induced in the rat paw by injection of phlogestic agent. Compound $2MB_1$, $2MB_8$, $2MB_5$, $2MB_3$ and $2MB_6$ exhibit satisfying anti-inflammatory activity while analgesic activity conducted by acetic acid induced writhing effect in mice while compound $2MB_1$, $2MB_4$ and $2MB_7$ having the good analgesic activity. The chemical structures of all newly synthesized compounds were confirmed by their IR, $^1H$ NMR and mass spectral data.
