Novel Hits in the Correction of deltaf508-Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) Protein: Synthesis, Pharmacological, and ADME Evaluation of Tetrahydropyrido[4,3-d]pyrimidines for the Potential Treatment of Cystic Fibrosis

Cystic fibrosis (CF) is a lethal genetic disease caused by mutations of the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) with a prevalence of the deltaF508 mutation. Whereas the detailed mechanisms underlying disease have yet to be fully elucidated, recent breakthroughs in clinical trials have demonstrated that CFTR dysfunction can be corrected by drug-like molecules. On the basis of this success, a screening campaign was carried out, seeking new drug-like compounds able to rescue deltaF508-CFTR that led to the discovery of a novel series of correctors based on a tetrahydropyrido[4,3-d]pyrimidine core. These molecules proved to be soluble, cell-permeable, and active in a disease relevant functional-assay. The series was then further optimized with emphasis on biological data from multiple cell systems while keeping physicochemical properties under strict control. The pharmacological and ADME profile of this corrector series hold promise for the development of more efficacious compounds to be explored for therapeutic use in CF.

Design, synthesis, and biological evaluation of indole carboxylic acid esters of podophyllotoxin as antiproliferative agents

A series of indole carboxylic acid conjugates of the podophyllotoxin were synthesized and evaluated as antiproliferative agents against two human chronic myeloid leukemia cell lines. Several compounds (In-2, In-8 and In-9) not only showed antiproliferative activity against normal K562 cells but also exhibited potent antineoplastic effect against resistant K562/VCR cells. The indole-6-formyl conjugate, In-9, revealed potent cytotoxic activity against K562 and K562/VCR cell lines, with IC50 values of 0.100 ¡À 0.008 and 0.227 ¡À 0.011 muM, respectively. Preliminary mechanism studies indicated that In-9 could disrupt the microtubule network in K562/VCR cells via occupying the colchicine binding site of the tubulin. Molecular dynamics simulation results revealed that the complex of In-9 and tubulin were stable. Furthermore, In-9 induced intracellular ROS generation, apoptosis, and cycle arrest at the G2 phase by inhibition of CDKs, loss of mitochondrial membrane potential and cleavage of caspase. In-9 simultaneously induced K562/VCR cells autophagy by upregulating the levels of Beclin1 and LC3-II, and exhibited anti-MDR ability by downregulating the levels of P-gp and MRP1. Finally, In-9 activated the AMPK and JNK signaling, and inhibited the ERK, P38, and PI3K/AKT/mTOR signaling in K562/VCR cells. In silico prediction indicated that In-9 mainly obeyed Lipinski rule for druglikeness. Together, In-9 possessed potent antiproliferative activity, and may be a promising agent for the potential treatment of resistant leukemia cancer.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 1670-82-2, you can also check out more blogs about1670-82-2

1,2,3-Thiadiazole substituted pyrazolones as potent KDR/VEGFR-2 kinase inhibitors

KDR kinase inhibition is considered to play an important role in regulating angiogenesis, which is vital for the survival and proliferation of tumor cells. Recently we disclosed a structure-based kinase inhibitor design strategy which led to the identification of a new class of VEGFR-2/KDR kinase inhibitors bearing heterocyclic substituted pyrazolones as the core template. Instability in a rat S9 preparation and poor iv PK profiles for most of these inhibitors necessitated exploration of new pyrazolones to identify new analogs with improved metabolic stability. Optimization of the heterocyclic moiety led to the identification of the thiadiazole series of pyrazolones (D) as potent VEGFR-2/KDR kinase inhibitors. SAR modifications, kinase selectivity profiling, and structural elements for improved PK properties were explored. Oral bioavailability up to 29% was achieved in the rat. Modeling results based on the Glide XP docking approach supported our postulation regarding the interaction of the lactam segment of the pyrazolones with the hinge region of the KDR kinase.

Direct Hiyama Cross-Coupling of (Hetero)arylsilanes with C(sp2)-H Bonds Enabled by Cobalt Catalysis

We report a chelation-assisted C-H arylation of various indoles with sterically and electronically diverse (hetero)arylsilanes enabled by cost-effective Cp*-free cobalt catalysis. Key to the success of this strategy is the judicious choice of copper(II) fluoride as a bifunctional sliane activator and catalyst reoxidant. This methodology features a broad substrate scope and good functional group compatibility. The synthetic versatility of this protocol has been highlighted by the gram-scale synthesis and late-stage diversification of biologically active molecules.

Palladium-Catalyzed Synthesis of Indoles by Reductive N-Heteroannulation of 2-Nitrostyrenes

A palladium-phosphine catalyzed reductive N-heteroannulation of 2-nitrostyrenes, in the presence of carbon monoxide, producing indoles has been developed. Indoles were obtained, in moderate to excellent yield, from substituted 2-nitrostyrenes having either electron-withdrawing (NO2 and CO2-Me) or electron-donating (Br, OH, Me, OMe, and OTf) substituents on the aromatic ring. Best results were obtained using palladium diacetate (6 mol %) together with triphenylphosphine (24 mol %) as the catalytic system, under 4 atm of carbon monoxide in acetonitrile at 70 C. Other palladium(II) and palladium(0) complexes also catalyze the reaction.
