Barvinchenko, V. N. published the artcileEffect of supramolecular interactions with cationic surfactants on adsorption of flavonoids on highly dispersed silica surface, Recommanded Product: N1,N10-Bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)-2-oxoethyl)-N1,N1,N10,N10-tetramethyldecane-1,10-diaminium chloride, the publication is Colloid Journal (2014), 76(2), 139-145, database is CAplus.

The effect of the cationic surfactants decamethoxine and miramistin on the physicochem. properties of the natural flavonoids quercetin and rutin is studied spectrophotometrically in the range of physiol. pH values. It is established that the interaction with these cationic surfactants changes the spectral characteristics of the flavonoids in solutions and essentially increases their adsorption on the surface of highly dispersed silica as compared with their aqueous solutions It is shown that the efficiency of flavonoid adsorption from decamethoxine and miramistin solutions is governed by solution pH, flavonoid hydrophobicity, and the nature of a cationic surfactant.

Baud, Matthias G. J. published the artcileNew Synthetic Routes to Triazolo-benzodiazepine Analogues: Expanding the Scope of the Bump-and-Hole Approach for Selective Bromo and Extra-Terminal (BET) Bromodomain Inhibition, SDS of cas: 209919-30-2, the publication is Journal of Medicinal Chemistry (2016), 59(4), 1492-1500, database is CAplus and MEDLINE.

We describe new synthetic routes developed toward a range of substituted analogs of bromo and extra-terminal (BET) bromodomain inhibitors I-BET762/JQ1 based on the triazolo-benzodiazepine scaffold. These new routes allow for the derivatization of the methoxyphenyl and chlorophenyl rings, in addition to the diazepine ternary center and the side chain methylene moiety. Substitution at the level of the side chain methylene afforded compounds targeting specifically and potently engineered BET bromodomains designed as part of a bump and hole approach. We further demonstrate that marked selectivity for the second over the first bromodomain can be achieved with an indole derivative that exploits differential interaction with an aspartate/histidine conservative substitution on the BC loop of BET bromodomains.

Liu, Yonghong published the artcileSodium Selenosulfate from Sodium Sulfite and Selenium Powder: An Odorless Selenylating Reagent for Alkyl Halides to Produce Dialkyl Diselenide Catalysts, Safety of 3-Chlorobenzylchloride, the publication is Synlett (2019), 30(14), 1698-1702, database is CAplus.

Na₂SeSO₃, which can be generated in situ by the reaction of Na₂SO₃ with Se power, was found to be an odorless reagent for the selenenylation of alkyl halides RX (R = Bu, cyclohexyl, 3-fluorobenzyl, etc.; X = Cl, Br) to produce dialkyl diselenides RSeSeR. By using aqueous EtOH as the solvent and avoiding the generation of a malodorous selenol intermediate, the selenylation reaction with Na₂SeSO₃ is much more environmentally friendly than conventional methods. Owing to the cheap and abundant starting materials and selenium reagents, the novel synthetic method reduces the production costs of dialkyl diselenides as organoselenium catalysts, thereby advancing practical applications of organoselenium-catalysis technologies.

Diao, Peng-Cheng published the artcileDiscovery of novel pyrimidine-based benzothiazole derivatives as potent cyclin-dependent kinase 2 inhibitors with anticancer activity, Formula: C7H7ClN2S, the publication is European Journal of Medicinal Chemistry (2019), 196-207, database is CAplus and MEDLINE.

To develop novel CDK2 inhibitors as anticancer agents, a series of novel pyrimidine-based benzothiazole derivatives I (R = 4-(S(O)₂NH₂), 4-(piperidin-1-yl), 3-F, etc.) and II (R¹ = H, F, Cl, Me, MeO; R² = H, Me, F; R³ = Me, NH₂) was designed and synthesized. Initial biol. evaluation demonstrated that some of target compounds displayed potent antitumor activity in vitro against five cancer cell lines. Especially, the analog II (R¹ = F; R² = H; R³ = NH₂) exhibited approx. potency with AZD5438 toward four cells including HeLa, HCT116, PC-3, and MDA-MB-231 with IC₅₀ values of 0.45, 0.70, 0.92, 1.80 μM, resp. More interestingly, the most highly active compound II (R¹ = F; R² = H; R³ = NH₂) in this study also possessed promising CDK2/cyclin A2 inhibitory activities with IC₅₀ values of 15.4 nM, which was almost 3-fold potent than pos. control AZD5438, and mol. docking studies revealed that the analog bound efficiently with the CDK2 binding site. Further studies indicated that compound II (R¹ = F; R² = H; R³ = NH₂) could induce cell cycle arrest and apoptosis in a concentration-dependent manner. These observations suggest that pyrimidine-benzothiazole hybrids represent a new class of CDK2 inhibitors and well worth further investigation aiming to generate potential anticancer agents.

Cummings, Maxwell D. published the artcileDiscovery and Early Development of TMC647055, a Non-Nucleoside Inhibitor of the Hepatitis C Virus NS5B Polymerase, Application of trimethyloxosulphonium chloride, the publication is Journal of Medicinal Chemistry (2014), 57(5), 1880-1892, database is CAplus and MEDLINE.

Structure-based macrocyclization of a 6-carboxylic acid indole chemotype has yielded potent and selective finger-loop inhibitors of the hepatitis C virus (HCV) NS5B polymerase. Lead optimization in conjunction with in vivo evaluation in rats identified several compounds showing (i) nanomolar potency in HCV replicon cells, (ii) limited toxicity and off-target activities, and (iii) encouraging preclin. pharmacokinetic profiles characterized by high liver distribution. This effort culminated in the identification of TMC647055 (I), a nonzwitterionic 17-membered-ring macrocycle characterized by high affinity, long polymerase residence time, and broad genotypic coverage. In vitro results of the combination of I with the HCV protease inhibitor TMC435 (simeprevir) supported an evaluation of this combination in patients with regard to virus suppression and resistance emergence. In a phase 1b trial with HCV genotype 1-infected patients, I was considered to be safe and well-tolerated and demonstrated potent antiviral activity, which was further enhanced in a combination study with TMC435.

Li, Er-dong published the artcile2,4-Disubstituted quinazolines targeting breast cancer cells via EGFR-PI3K, Name: 1-(Chloromethyl)-4-(trifluoromethyl)benzene, the publication is European Journal of Medicinal Chemistry (2019), 36-47, database is CAplus and MEDLINE.

A series of novel 2,4-disubstituted quinazolines I [R = hexyl, cyclopentyl, Ph, etc.] were synthesized and evaluated for their anti-tumor activity against five human cancer cells (MDA-MB-231, MCF-7, PC-3, HGC-27 and MGC-803) using MTT assay. Among them, compound I [R = 4-F₃CC₆H₄] showed the most potent cytotoxicity against breast cancer cells. Compound I [R = 4-F₃CC₆H₄] also significantly inhibited the colony formation and migration of MDA-MB-231 and MCF-7 cells. Meanwhile, compound I [R = 4-F₃CC₆H₄] induced cell cycle arrest at G1 phase and cell apoptosis, as well as increased accumulation of intracellular ROS. Furthermore, compound I [R = 4-F₃CC₆H₄] exerted antitumor effects in-vitro via decreasing the expression of anti-apoptotic protein Bcl-2 and increasing the pro-apoptotic protein Bax and p53. Mechanistically, compound I [R = 4-F₃CC₆H₄] markedly decreased p-EGFR and p-PI3K expression, which revealed that compound I [R = 4-F₃CC₆H₄] targeted breast cancer cells via interfering with EGFR-PI3K signaling pathway. Mol. docking suggested that compound I [R = 4-F₃CC₆H₄] could indeed bind into the active pocket of EGFR. All the findings suggest that compound I [R = 4-F₃CC₆H₄] might be a valuable lead compound for antitumor agents targeting breast cancer cells.

An unprecedented two-step, one-pot synthesis of benzimidazothiadiazine 5,5-dioxides is presented. Reaction condition based regioselectivity has been achieved where fused benzimidazo[1,2-b][1,2,4]thiadiazines are exclusively formed under thermal conditions, whereas benzimidazo[2,1-c][1,2,4]thiadiazines were created only under microwave irradiation The salient features of this protocol include a regioselective sulfonylation of 2-aminobenzimidazole with o-halo sulfonyl chlorides followed by N-C bond formation. The acid forms of these fused regioisomers have been used to introduce novel guanidine-containing isocoumarin frameworks.
