A Direct Synthesis of 2-(omega-Carboxyalkyl)isoflavones from ortho-Hydroxylated Deoxybenzoins

As part of a program focused on the development of new antineoplastic agents based on scaffolds found in natural products, we explored the isoflavone family as potential enzyme inhibitors. We required biotin-modified isoflavones to identify potential biological targets, and we selected the C-2 position in isoflavones as an attachment site for an alkyl group bearing a terminal carboxylic acid to which we could attach a biotin derivative. The base-catalyzed condensation of 2,4-dihydroxy-substituted deoxybenzoins with cyclic anhydrides mediated by a combination of triethylamine and 1,8-diazabicyclo[5.4.0]undec-7-ene led to an efficient synthesis of the desired 2-(omega-carboxyalkyl)isoflavones with functional groups at C-5, 6 and 7 and with various substituents in the C-3 phenyl group.

Synthesis and biological evaluation of a series of benzoxazole/ benzothiazole-containing 2,3-dihydrobenzo[b][1,4]dioxine derivatives as potential antidepressants

A series of benzoxazole/benzothiazole-2,3-dihydrobenzo[b][1,4]dioxine derivatives (5a-5d and 8a-8j) was synthesized. Compounds were evaluated for binding affinities at the 5-HT1A and 5-HT2A receptors. Antidepressant activities of the compounds were screened using the forced swimming test (FST) and the tail suspension test (TST). The results indicated that the compounds exhibited high affinities for the 5-HT1A and 5-HT2A receptors and showed a marked antidepressant-like activity. Compound 8g exhibited high affinities for the 5-HT1A (Ki = 17 nM) and 5-HT2A (Ki = 0.71 nM) receptors; it also produced a decrease of the immobility time and exhibited potent antidepressant-like effects in the FST and TST in mice.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 70918-54-6, help many people in the next few years.SDS of cas: 70918-54-6

Synthesis and cytotoxic activity of novel tetrahydrobenzodifuran?imidazolium salt derivatives

The synthesis of a series of novel 4-substituted 2,3,6,7-tetrahydrobenzo [1,2-b;4,5-b?]difuran?1H-imidazolium salts is presented. The biological properties of the compounds were evaluated in vitro against a panel of human tumor cell lines. Results suggest that the 5,6-dimethyl-benzimidazole or 2-methyl-benzimidazole ring, and substitution of the imidazolyl-3-position with a 2-naphthylmethyl substituent or 2-naphthylacyl substituent, were important to the cytotoxic activity. Notably, 3-(2-Naphthylmethyl)-1-((2,3,6,7-tetrahydrobenzo[1,2-b;4,5-b?]difuran-4-yl)methyl)-1H-5,6-dimethyl-benzimidazol-3-ium bromide (42) was found to be the most potent derivative against five human tumor cell lines with IC50 values of 1.06?4.34?muM and more selective towards SMMC-7721, A549 and SW480 cell lines. 3-(2-Naphthylacyl)-1-((2,3,6,7-tetrahydrobenzo[1,2-b;4,5-b?]difuran-4-yl)methyl)-1H-2-methyl-benzimidazol-3-ium bromide (37) showed higher selectivity to SMMC-7721 and MCF-7 cell lines with IC50 values 2.7-fold and 8.4-fold lower than DDP. Study regarding to the antitumor mechanism of action showed that compound 37 could induce cell cycle G1 phase arrest and apoptosis in SMMC-7721 cells.

Synthetic Approaches to Phthalazines: C-N Bond Cleavage in 2′-Benzylbenzohydrazides During Reaction with Polyphosphoric Acid

Reaction of 2′-benzylbenzohydrazides with concentrated polyphosphoric acid gave 2,5-diaryl-1,3,4-oxadiazoles and a polybenzyl.Cyclodehydration to phthalazines was not observed.It is inferred from product substitution patterns that CH2-N bond cleavage occurs with polybenzyls forming from the benzyl moiety and oxadiazoles from the benzohydrazide fragment.Other reported reactions which generate benzyl fragments lead to bibenzyl and are considered to involve trapping of the cleavage products within a solvent cage.The observed production of polybenzyls is therefore interpreted in terms of the formation of free benzyl fragments.A tetrahydrophthalazine derivative was produced from the addition of diethyl azodicarboxylate to the photodiene of o-methylbenzophenone, but this could not be converted into a phthalazine.

Convergent catalytic asymmetric synthesis of camptothecin analog GI147211C

The topoisomerase I inhibitor GI147211C (4) was discovered at Glaxo Wellcome and shown to have promising anti-cancer properties. In order to fully assess the clinical potential of 4, an improved synthesis of the drug substance was required. Herein is described a convergent catalytic asymmetric synthesis of 4 which utilizes as key steps, two Heck reactions, a Sharpless asymmetric dihydroxylation reaction, and a Mitsunobu reaction. A 2-chloroquinoline is shown to be a viable substrate for the final Heck reaction to generate the camptothecin nucleus.

Visible-Light-Mediated Aerobic Oxidation of Organoboron Compounds Using in Situ Generated Hydrogen Peroxide

A simple and general visible-light-mediated oxidation of organoboron compounds has been developed with rose bengal as the photocatalyst, substoichiometric Et3N as the electron donor, as well as air as the oxidant. This mild and metal-free protocol shows a broad substrate scope and provides a wide range of aliphatic alcohols and phenols in moderate to excellent yields. Notably, the robustness of this method is demonstrated on the stereospecific aerobic oxidation of organoboron compounds.
