A new series of 1-(4-{5-Amino-6-fluoro-1-[2'-(2H-tetrazole-5-yl)-biphenyl-4-ylmethyl]-1Hbenzoimidazol-2-yl}-phenyl)-3-chloro-4-(Substituted -phenyl)-azetidin-2-one derivatives MCS 06[1-15] has been synthesized and subjected to evaluate their antihypertensive activity. All the synthesized compounds of the series elicit remarkable activity in comparison to standard drug (Losartan). Structures of ...

Several substituted-benzimidazole 3-(4-{5-Amino-6-fluoro-1-[2'-(1H-tetrazole-5-yl)-biphenyl-4ylmethyl]-1H-benzoimidazol-2-yl}-phenyl) -2-(substituted)thiazolidin-4-one were synthesized by condensation of various steps with various substituted aryl aldehydes reaction. Elemental analysis, IR, 1HNMR and mass spectral data confirmed the structure of the newly synthesized compounds. Synthesized and ...

[reaction: see text] A practical and environmentally friendly organocatalytic strategy designed to mimic the DHAP aldolases has been developed and shown to be effective in the preparation of carbohydrates and aminosugars. (S)-Proline and (S)-2-pyrrolidine-tetrazole catalyzed the aldol reaction between dihydroxy acetone variants such as 1,3-dioxan-5-one and 2,2-dimethyl-1,3-dioxan-5-one with ald...

A non-radioactive cell-free assay was developed to quantitatively determine inhibition of plant-type phytoene desaturase by bleaching herbicides. An active desaturase was prepared from an appropriately cloned E. coli transformant. Another E. coli transformant was used to produce the required phytoene. Phytofluene and zeta-carotene, the products of the desaturase reaction, were either determined...

An innovative one-step synthesis towards β-aryl-β,β-difluorocarbamates and β-aryl-β,β-difluoroazides is presented. The described approach relies on the use of α-fluorostyrene substrates in a radical addition/fluorination reaction with N-centered radicals presence Selectfluor®. best results were obtained for azidofluorination reaction. resultant further transformed into Nitrogen-based heterocycl...
