The synthesis and evaluation of some bioisosteres of thalidomide metabolites for antiangiogenic and anticancer activity on multiple myeloma are described in this article. Four compounds, di-Et 2-(thiophene-2-sulfonamido) pentanedioate, N1,N5-diethyl-2-(thiophene-2-sulfonamido) pentanediamide, N1,N5-dihexyl-2-(thiophene-2-sulfonamido) pentanediamide, and N-(1,5-dioxo-1,5-bis(2-phenylhydrazinyl)pentan-2-yl)thiophene-2-sulfonamide exhibit cytotoxic effect on human multiple myeloma cell line (RPMI8226) with IC50 (in μM) values 3.33, 0.75, 1.23, and 3.28, resp. The in vitro studies on human umbilical vein endothelial cells (HUVEC) and normal African green monkey kidney epithelial cells (Vero cell line) concluded that these compounds bear antiangiogenic properties and are selectively cytotoxic to cancer cells. Except for N-(1,5-dioxo-1,5-bis(2-phenylhydrazinyl)pentan-2-yl)Thiophene-2-sulfonamide, it was found to be toxic to normal epithelial cells. The trypan blue dye exclusion method was used to conduct an antiproliferative assay of the active compounds on HUVECs. The phosphorylation inhibition assay on Vascular Endothelial Growth Factor Receptor-2 Tyr-1175 (VEGFR-2 Tyr-1175) revealed that N1,N5-diethyl-2-(thiophene-2-sulfonamido) pentanediamide and N1,N5-dihexyl-2-(thiophene-2-sulfonamido) pentanediamide are active, indicating that the mols. have antiangiogenic activity by targeting VEGFR-2 Tyr-1175, a key autophosphorylation site that regulates pro-angiogenic responses. On CDOCKER, a mol. docking study of the most active compound N1,N5-diethyl-2-(thiophene-2-sulfonamido) pentanediamide with VEGFR-2 revealed that they might interact with the essential amino acid residues, with a binding energy of -105.304 kcal/mol. In the part of experimental materials, we found many familiar compounds, such as Thiophene-2-sulfonyl chloride(cas: 16629-19-9Quality Control of Thiophene-2-sulfonyl chloride)

Application of 620-20-2On March 17, 2021, Zhang, Xiao; Wang, Yiping; Xu, Zhiping; Shao, Xusheng; Liu, Zewen; Xu, Xiaoyong; Maienfisch, Peter; Li, Zhong published an article in Journal of Agricultural and Food Chemistry. The article was 《Design, Synthesis, and Synergistic Activity of Eight-Membered Oxabridge Neonicotinoid Analogues》. The article mentions the following:

Insecticide synergists are sought-after due to their potential in improving the pesticide control efficacy with a reduced dose of an active ingredient. We previously reported that a cis-configuration neonicotinoid (IPPA08) exhibited specific synergistic activity toward neonicotinoid insecticides. In this study, we synthesized a series of structural analogs of IPPA08 by converting the pyridyl moiety of IPPA08 into Ph groups, via facile double-Mannich condensation reactions between nitromethylene compounds and glutaraldehyde. All of the oxabridged neonicotinoid compounds were found to increase the toxicity of imidacloprid against Aphis craccivora. Notably, compound (I) at 0.75 mg/L lowered the LC50 value of imidacloprid against A. craccivora by 6.54-fold, while a 3.50-fold reduction of the LC50 value was observed for IPPA08. The results of bee toxicity test showed that compound I display selectivity in its effects on imidacloprid toxicity against the honey bee (Apis mellifera L.). In summary, replacing the pyridyl ring with a Ph ring was a viable approach to obtain a novel synergist with oxabridged moiety for neonicotinoid insecticides. The experimental process involved the reaction of 3-Chlorobenzylchloride(cas: 620-20-2Application of 620-20-2)

The article was titled 《Synthesis and biological evaluation of isatin derivatives containing 1,3,4-thiadiazole as potent a-glucosidase inhibitors》.Reference of 3-Chlorobenzylchloride The article contains the following contents:

A series of isatin derivatives containing 1,3,4-thiadiazole derivatives I [R = 2-F, 3-CN, 4-Cl, etc.] were designed and synthesized. All newly synthesized compounds I were evaluated for their α-glucosidase inhibitory activity with resveratrol as pos. control in-vitro. Except for compounds I [R = 2-CN, 3-CN], all of the compounds I showed a potent inhibitory activity against α-glucosidase with IC50 values in the range of 3.12 ± 1.25 to 45.95 ± 1.26μM and the purity of these compounds were greater than 95%. The IC50 values were being compared to the standard resveratrol (IC50 = 22.00 ± 1.15μM) and it was found that compounds I [R = H, 2-F, 2-Cl, 3-Cl, 4-Cl, 2-Br] were found to be more active than resveratrol. Specifically,I [R = 4-Cl] exhibited the most potent α-glucosidase inhibitory activity with IC50 value of 3.12 ± 1.25μM. The kinetic anal. revealed that compound I [R = 4-Cl] was noncompetitive inhibitor. Structure activity relationship was established for all compounds I. Furthermore, the binding interactions of compound I [R = 4-Cl] with the active site of α-glucosidase were confirmed through mol. docking. This study was identified a new class of potent α-glucosidase inhibitors for further investigation.
