In a patent, 214894-89-0, name is 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine, introducing its new discovery. Application In Synthesis of 5-(Bromomethyl)-2,3-dihydro-1,4-benzodioxine

The mechanism of the SmI2-mediated reduction of unactivated esters has been studied using a combination of kinetic, radical clocks and reactivity experiments. The kinetic data indicate that all reaction components (SmI2, amine, H2O) are involved in the rate equation and that electron transfer is facilitated by Bronsted base assisted deprotonation of water in the transition state. The use of validated cyclopropyl-containing radical clocks demonstrates that the reaction occurs via fast, reversible first electron transfer, and that the electron transfer from simple Sm(II) complexes to aliphatic esters is rapid. Notably, the mechanistic details presented herein indicate that complexation between SmI2, H2O and amines affords a new class of structurally diverse, thermodynamically powerful reductants for efficient electron transfer to carboxylic acid derivatives as an attractive alternative to the classical hydride-mediated reductions and as a source of acyl-radical equivalents for C-C bond forming processes.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research.

Compound 8H is a phenylcinnamide that induces G2/M-phase cell cycle arrest and cell death in cancer cell lines. Here we show that 8H exerts its cytotoxic activity through disruption of microtubule dynamics in vitro and in cell culture. A series of cinnamide derivatives were synthesized and evaluated, and several new compounds were identified that improve on the activity of the parent compound, with IC50 values for induction of cell death ranging from 1 to 10 muM. Notably, these compounds retain potency in the HL-60/VCR leukemia cell line, which is resistant to antimitotic cancer drugs vincrisitine and paclitaxel through up-regulation of P-glycoprotein drug efflux pumps. As P-glycoprotein expression is often responsible for drug resistance in cancer and the exclusion of compounds from the central nervous system, 8H and its derivatives merit further examination as potential antimitotic therapeutics, specifically for brain cancers and cancers that are resistant to standard antimitotic agents.

Two series of nitrogenous heterocycle compounds-1,2,4-trisubstituted imidazoles and 1,3,5-trisubstituted pyrazoles have been synthesized and evaluated for their ALK5 inhibitory activity and cytotoxicity in TGFbeta-Smad2 assay and MTT assay, respectively. The ALK4/5/7 inhibitory activity of some compound was also evaluated in ALK4/5/7 autophosphorylation assays. Compounds 6c and 14c showed relatively potent ALK5 inhibition while weak cytotoxicity. At the same time, compounds 6c and 14c display relatively better ALK5 selectivity versus ALK4/ALK7 (nearly 10-fold) compared with SB431542, a well known ALK5 inhibitor. Compound 6g2 proved to be a moderately selective ALK4 inhibitor versus ALK5 and ALK7 (>10-fold). The binding mode of 14c generated by flexible docking study shows that 14c fits well into the site cavity of ALK5 by forming several tight interactions.
