New research progress on 589-87-7 in 2021. Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. 589-87-7, Name is 1-Bromo-4-iodobenzene, molecular formurla is C6H4BrI. In a document, author is Duarte, CD, introducing its new discovery. Safety of 1-Bromo-4-iodobenzene.
We describe herein the structural optimization of new piperamide analogues, designed from two natural prototypes, piperine 1 and piper-dardine 2, obtained from Piper tuberculatum Jacq. (Piperaceae). Molecular modeling studies using semiempirical AMI method were made in order to establish rational modifications to optimize them by molecular simplification. The targeted compounds (10) and (11) were respectively obtained using benzaldehyde (12) and para-anisaldehyde (13) as starting materials. H-1 NMR spectra showed that the target compounds were diastereoselectively obtained as the (E)-isomer, the same geometry of the natural prototypes. These new synthetic amides presented significant hypotensive effects in cardiovascular essays using in vivo methodologies. Compound 11 (N-[5-(4′-methoxyphenyl)2(E)-pentenoyl]thiomorpholine) showed a potency 10,000 times greater than its prototype 5, evidencing an optimization of the molecular architecture for this class of hypotensive drug candidates.
