Heterocyclic Building Blocks-Benzothiophene

Electric Literature of 35212-85-2, Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. In a article, 35212-85-2, molcular formula is C10H9NO2S, introducing its new discovery.

Methyl and phenyl derivatives containing the [1]Benzothieno[3,2-d]pyrimidin-4-one system have been synthesized and tested as inhibitors of COX-1 and COX-2 activities in human whole blood (HWB) ex vivo; all compounds turned out to be weak inhibitors of COX- 1 activity, as deduced from the TXB2 (thromboxane B) generation; the acid phenyl derivative 11 b was an interesting inhibitor of COX-2 activity, as deduced from the PGE2 (prostaglandine E) generation.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 35212-85-2

In vitro and ex vivo efficacies of four series of benzo[b]thiophene-2-carboxylic acid derivatives were studied against Mycobacterium tuberculosis H37Ra (MTB). Benzo[b]thiophenes were also tested in vitro against multidrug resistant Mycobacterium tuberculosis H37Ra (MDR-MTB), and 7b was found to be highly active against A- and D-MDR-MTB/MTB (MIC ranges 2.73-22.86 mug/mL). The activity of all benzo[b]thiophenes against M. bovis BCG (BCG) was also assessed grown under aerobic and under conditions of oxygen depletion. Compounds 8c and 8g showed significant activity with MICs of 0.60 and 0.61 mug/mL against dormant BCG. The low cytotoxicity and high selectivity index data against human cancer cell lines, HeLa, Panc-1, and THP-1 indicate the potential importance of the development of benzo[b]thiophene-based 1,3-diketones and flavones as lead candidates to treat mycobacterial infections. Molecular docking studies into the active site of DprE1 (Decaprenylphosphoryl-beta-d-ribose-2?-epimerase) enzyme revealed a similar binding mode to native ligand in the crystal structure thereby helping to understand the ligand-protein interactions and establish a structural basis for inhibition of MTB. In summary, its good activity in in vitro and ex vivo model, as well as its activity against multidrug-resistant M. tuberculosis H37Ra in a potentially latent state, makes 7b an attractive drug candidate for the therapy of tuberculosis.

A series of novel 1-substituted-2-aryl imidazoles (SAI) were designed and synthesized based on our previously reported ABI (2-Aryl-4-Benzoyl Imidazole) analogs and on the structure of combretastatin A-4 (CA-4). These compounds showed potent antiproliferative activities against six human cancer cell lines with IC50 values in nano molar range. Among them, compound 3X exhibited the best anticancer activity with an average IC50 value of ?100 nM. The compound maintains the mechanism of action by inhibiting tubulin polymerization, thus causing cell arrest at G2/M phase and apoptosis. In vivo efficacy studies indicated that 3X was highly effective in suppressing tumor growth in a MDA-MB-468 xenograft model of nude mouse with a TGI (Tumor Growth Suppression) of 77% at 60 mg/kg without causing significant toxicity. In addition, 3X displayed significantly better water solubility (36.70 mug/mL) than CA-4 (2.83 mug/mL). Molecular modeling study indicated that 3X binds well to the colchicine binding site in tubulin. Our results suggest that the novel SAI analogs deserve further investigation as potential anticancer agents.

Haloaroylmethylidenephosphoranes 3 can be subjected to Pd(o) mediated C-C coupling reactions to yield diaryl-, arylhetaryl-, dihetaryl, arylethenylaryl/hetaryl- and arylethynylaryl/hetaryl-carbonylmethylidenephosphoranes 4-9. Suzuki-Kumada reactions can also be run in a one-step procedure from (haloaroylmethyl)triphenylphosphonium bromides 2. Compounds 4-9 are air-stable phosphoranes which undergo formal Wittig-olefination reactions with aldehydes 10 under benzoic acid catalysis. C-C coupling reaction and Wittig olefination can also be performed in a one-step procedure. Preliminary experiments have been performed to carry out the synthesis on a solid support. Applications to the chain elongation and functionalisation of the chain terminus in a C-7 substituted estra-1,3,5(10)-triene 14 and a C-16 substituted estra-1,3,5(10),6-tetraene 12 are shown.

A kinetic study of the reversible deprotonation of benzofuran-3(2H)-one (3H-O) and benzothiophene-3(2H)-one (3H-S) by amines and hydroxide ion in water at 25 C is reported. The respective conjugate bases, 3–O and 3–S, represent benzofuran and benzothiophene derivatives, respectively, and thus are aromatic. The main question addressed in this paper is whether this aromaticity has the effect of enhancing or lowering intrinsic barriers to proton transfer. These intrinsic barriers were either determined from Bronsted plots for the reactions with amines or calculated on the basis of the Marcus equation for the reaction with OH-; they were found to be lower for the more highly aromatic benzothiophene derivative, indicating that aromaticity lowers the intrinsic barrier. It is shown that the reduction in the intrinsic barrier is not an artifact of other factors such as inductive, steric, resonance, polarizability, and pi-donor effects, although these factors affect the intrinsic barriers in a major way. Our results imply that aromatic stabilization of the transition state is ahead of proton transfer; this contrasts with simple resonance effects, which typically lag behind proton transfer at the transition state, thereby increasing intrinsic barriers.

A strategy for the selective phosphonation of benzofuran and benzothiophene with trialkyl phosphites was developed. In these reactions, the C?H phosphonation of benzofurans or benzothiophenes at the C2 or C3 position with trialkyl phosphites was successfully achieved without directing groups by using a copper catalyst. Additionally, the C5 phosphonation of furan was successful under the same conditions.
