The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1-(Bromomethyl)-2-iodobenzene(SMILESS: BrCC1=C(I)C=CC=C1,cas:40400-13-3) is researched.Formula: C46H46O4P2Pd2. The article 《Substituted dienes prepared from betulinic acid – Synthesis, cytotoxicity, mechanism of action, and pharmacological parameters》 in relation to this compound, is published in European Journal of Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:40400-13-3).

A set of new substituted dienes were synthesized from betulinic acid by its oxidation to 30-oxobetulinic acid followed by the Wittig reaction. Cytotoxicity of all compounds was tested in vitro in eight cancer cell lines and two noncancer fibroblasts. Almost all dienes were more cytotoxic than betulinic acid. Four compounds had IC50 below 5μmol/L; I and II were selected for studies of the mechanism of action. Cell cycle anal. revealed an increase in the number of apoptotic cells at 5 x IC50 concentration, where activation of irreversible changes leading to cell death can be expected. Both I and II led to the accumulation of cells in the G0/G1 phase with partial inhibition of DNA/RNA synthesis at 1 x IC50 and almost complete inhibition at 5 x IC50. Interestingly, compound II at 5 x IC50 caused the accumulation of cells in the S phase. Higher concentrations of tested drugs probably inhibit more off-targets than lower concentrations Mechanisms disrupting cellular metabolism can induce the accumulation of cells in the S phase. Both compounds I and II trigger selective apoptosis in cancer cells via intrinsic pathway, which we have demonstrated by changes in the expression of the crucial apoptosis-related protein. Pharmacol. parameters of derivative I were superior to II, therefore I was the finally selected candidate for the development of anticancer drug.

Light-promoted, copper catalyzed cage C-H arylation of o-carboranes with aryl halides has been achieved, leading to the facile synthesis of a variety of 1-aryl-o-carboranes and o-carborane-fused cyclics. This method has the following features: (1) using o-carboranes instead of prefunctionalized iodocarboranes as starting materials; (2) employing earth abundant copper as a catalyst; and (3) room-temperature reaction. Control experiments suggest that the reaction proceeds via Cu-catalyzed radical coupling.

X-ray imaging functionalization of biodegradable polyesters is a great demand and challenge in biomedical applications. In this work, a strategy of in-chain functionalization through the combination of ring opening copolymerization and oxime “”Click”” postfunctionalization was developed towards X-ray opaque polylactide copolymers. A functionalized cyclic carbonate was first synthesized and used as comonomer of polylactide copolymers, which were subjected to postfunctionalization of oxime “”Click”” reaction towards iodinated polylactide copolymers. The chem. structure and phys. properties of the target products were traced and confirmed. In vitro cytotoxicity evaluation with 3T3-Swiss albino by Alamar blue demonstrated a low cytotoxicity. The X-ray radiopacity was analyzed by Micro-CT and quantified by Hounsfield Units value, which could be tailorable by the feedstock. It is a promising X-ray visible implantable biomaterial in biomedical applications.

Now I present to you an article called Thiophene Derivative-Loaded Nanoparticles Mediate Anticancer Activity Through the Inhibition of Kinases and Microtubule Assembly, published in 2021-07-31, which mentions a compound: 40400-13-3, mainly applied to thiophene nanoparticle anticancer kinase inhibition microtubule assembly; Antimitotic drugs; Caspase activity; Cell cycle arrest; Microtubule assembly; Nanoparticles; Tetrahydrobenzo[b]thiophenes; Tubulin polymerization, COA of Formula: C7H6BrI.

Different tetrahydrobenzo[b]thiophene derivatives are explored as new tubulin polymerization destabilizers to arrest tumor cell mitosis. A series of compounds incorporating the tetrahydrobenzo[b]thiophene scaffold are synthesized, and their biol. activities are investigated. The cytotoxicity of each of the synthesized compounds is assessed against a range of cell lines. Specifically, the benzyl urea tetrahydrobenzo[b]thiophene derivative, 1-benzyl-3-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)urea (BU17), is identified as the most potent compound with broad-spectrum antitumor activity against several cancer cell lines. The potential mechanism(s) of action are investigated where dose-dependent G2/M accumulation and A549 cell cycle arrest are detected. Addnl., A549 cells treated with BU17 express enhanced levels of caspase 3 and 9, indicating the induction of apoptosis. Furthermore, it is found that BU17 inhibits WEE1 kinase and targets tubulin by blocking its polymerization BU17 is also formulated into PLGA nanoparticles, and it is demonstrated that BU17-loaded nanoparticles can significantly enhance antitumor activity compared to the soluble counterpart.

Category: chiral-phosphine-ligands. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 1-(Bromomethyl)-2-iodobenzene, is researched, Molecular C7H6BrI, CAS is 40400-13-3, about Selenenate Anions (PhSeO-) as Organocatalyst: Synthesis of trans-Stilbenes and a PPV Derivative.

The selenenate anion (RSeO-) is introduced as an active organocatalyst for the dehydrohalogenation coupling of benzyl halides to form trans-stilbenes. It is shown that RSeO- is a more reactive catalyst than the previously reported sulfur analogs (sulfenate anion, RSO-) and selenolate anions (RSe-) in the aforementioned reaction. This catalytic system was also applied to the benzylic-chloromethyl-coupling polymerization (BCCP) of a bis-chloromethyl arene to form ppv (poly(p-phenylene vinylene))-type polymers with high yields, Mn (average mol. weight) up to 13,000 and D (dispersity) of 1.15.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Preprint, ChemRxiv called Mapping ambiphile reactivity trends in the anti-(hetero)annulation of non-conjugated alkenes via Pd(II)/Pd(IV) catalysis, Author is Ni, Hui-Qi; Cooper, Phillippa; Yang, Shouliang; Wang, Fen; Sach, Neal; Bedekar, Pranali G.; Donaldson, Joyann S.; Tran-Dube, Michelle; McAlpine, Indrawan J.; Engle, Keary M., which mentions a compound: 40400-13-3, SMILESS is BrCC1=C(I)C=CC=C1, Molecular C7H6BrI, Recommanded Product: 1-(Bromomethyl)-2-iodobenzene.

A systematic evaluation of different ambiphilic organohalides, e.g., N-(2-iodobenzyl)-4-(trifluoromethyl)benzenesulfonamide for their ability to participate in anti-selective carbo- or heteroannulation with non-conjugated alkenyl amides e.g., N-(quinolin-8-yl)but-3-enamide under Pd catalysis has been described. Detailed optimization of reaction conditions has led to protocols for synthesizing tetrahydropyridines I (R = H, Me; R1 = H, Me, Ph; X = tosyl, 4-CNC6H4S(O)2), tetralins II [R2 = H, Me, OMe, etc.; R3 = H, CN; R4 = C(C(O)OMe)2, C(C(O)OEt)2, C(CN)(C(O)OEt), etc.], pyrrolidines III (R5 = Ts, OBn, Ph), and other carbo/heterocyclic cores via [n + 2] (n = 3-5) (hetero)annulation. Expansion of scope to otherwise unreactive ambiphilic haloketones through Pd(II)/amine co-catalysis is also demonstrated. Compared to other annulation processes, this method proceeds via a distinct Pd(II)/Pd(IV) mechanism involving Wacker type directed nucleopalladation. This distinction results in unique reactivity and selectivity patterns, as revealed through assessment of reaction scope and competition experiments
