The article was titled 《Discovery of the cancer cell selective dual acting anti-cancer agent (Z)-2-(1H-indol-3-yl)-3-(isoquinolin-5-yl)acrylonitrile (A131)》.Application of 89245-35-2 The article contains the following contents:

Selective targeting of cancer cells over normal cells is a key objective of targeted therapy. However few approaches achieve true mechanistic selectivity resulting in debilitating side effects and dose limitation. In this work we describe the discovery of A131 (4a), a new agent with an unprecedented dual mechanism of action targeting both mitosis and autophagy. Compound 4a was first identified in a phenotypic screen in which HeLa cells treated with 4a manifested mitotic arrest along with formation of multiple vesicles. Further investigations showed that 4a causes an increase in mitotic marker pH3 and autophagy marker LC3. Importantly 4a induces cell death in cancer cells while sparing normal cells which regrow after 4a is removed. Dual activities against pH3 and LC3 markers are required for cancer cell selectivity. An extensive SAR investigation confirmed 4a as the optimal dual inhibitor with potency against a panel of 30 cancer cell lines (average antiproliferative GI50 1.5μM). In a mouse model of paclitaxel-resistant colon cancer, 4a showed 74% tumor growth inhibition when administered at a dose of 20mg/kg IP twice a day.

The authors have developed a highly efficient aryl migration from an aryl ether to a carboxylic acid group through retro-Smiles rearrangement by visible-light photoredox catalysis at ambient temperature Transition metals and a stoichiometric oxidant and base are avoided in the transformation. Inspired by the high efficiency of this transformation and the fundamental importance of C-O bond cleavage, the authors developed a novel approach to the C-O cleavage of a biaryl ether to form two phenolic compounds, as demonstrated by a 1-pot, two-step gram-scale reaction under mild conditions. The aryl migration exhibits broad scope and can be applied to the synthesis of pharmaceutical compounds, such as guacetisal. Primary mechanistic studies indicate that the catalytic cycle occurs by a reductive quenching pathway.4-Bromo-2-fluorobenzonitrile(cas: 105942-08-3Category: nitriles-buliding-blocks) was used in this study.

Reference of 4-Bromo-2-fluorobenzonitrile. The article was titled 《Manufacture of the PI3K β-Sparing Inhibitor Taselisib. Part 1: Early-Stage Development Routes to the Bromobenzoxazepine Core》. The information in the text is summarized as follows:

Two convergent regioselective routes for the synthesis of the tetracyclic imidazobenzoxazepine triazole I, a key intermediate toward the synthesis of taselisib, are described. In the first-generation route, a chemoselective Negishi cross-coupling reaction was developed between iodoimidazole II and 1-isopropyl-3-methyl-1H-1,2,4-triazole, which enabled the delivery of initial kilogram quantities of I. Because of the inefficiencies in the preparation of the imidazole II, a second-generation route via a highly regioselective imidazole ring formation between α-chloroketone III and aryl amidine IV was developed. The resulting imidazole V provided the handle to efficiently install the seven-membered benzoxazepine ring system in one pot with two-step N-alkylation and SNAr tandem reactions.

And the article was published in European Journal of Medicinal Chemistry in 2019. Formula: C8H6BrN The author mentioned the following in the article:

Herein we report the design and synthesis of novel N-substituted isatins-SLC-0111 hybrids. A structural extension approach was adopted via N-alkylation and N-benzylation of isatin moiety to enhance the tail hydrophobic interactions within the carbonic anhydrase (CA) IX active site. Thereafter, a hybrid pharmacophore approach was utilized via merging the pharmacophoric elements of isatin and SLC-0111 in a single chem. framework. As planned, a substantial improvement of inhibitory profile of the target hybrids (KIs: 4.7-86.1 nM) towards hCA IX in comparison to N-unsubstituted leads (KIs: 192-239 nM), was achieved. Mol. docking of the designed hybrids in CA IX active site unveiled, as planned, the ability of N-alkylated and N-benzylated isatin moieties to accommodate in a wide hydrophobic pocket formed by T73, P75, P76, L91, L123 and A128, establishing strong van der Waals interactions. Hybrid I displayed good anti-proliferative activity under hypoxic conditions towards breast cancer MDA-MB-231 and MCF-7 cell lines (IC50 = 7.43 ± 0.28 and 12.90 ± 0.34 μM, resp.). Also, I disrupted the MDA-MB-231 cell cycle via alteration of the Sub-G1 phase and arrest of G2-M stage. Addnl., I displayed significant increase in the percent of annexinV-FITC pos. apoptotic cells from 1.03 to 18.54%. Furthermore, I displayed potent VEGFR-2 inhibitory activity (IC50 = 260.64 nM). Collectively, these data suggest I as a promising lead mol. for the development of effective anticancer agents.
