New homocamptothecins: Synthesis, antitumor activity, and molecular modeling

Homocamptothecins (hCPTs) represent a class of new emerging antitumor agents, which contains a seven-membered beta-hydroxylactone in place of the conventional six-membered alpha-hydroxylactone ring (E ring) of camptothecins. Some novel 7-substituted hCPTs were designed and synthesized based on a newly developed synthetic route which couples ring A with ring C, E and D. Most of the synthesized compounds exhibit very high cytotoxic activity on tumor cell line A549. Some compounds, such as 9b, 9l, and 9y, show broad in vitro antitumor spectrum and are more potent than topotecan. Three-dimensional quantitative structure-activity relationship (3D-QSAR) methods, CoMFA and CoMSIA, were applied to explain the structure-activity relationship (SAR) of the synthesized compounds. Furthermore, molecular docking was used to clarify the binding mode of the synthesized compounds to human DNA topoisomerase I. The important hydrophobic, base-pair stacking, and hydrogen-bonding interactions were observed between the hCPT derivatives and their receptor. The results from molecular modeling will guide the design of novel hCPTs with higher antitumor activity.

Synthesis of some new N-substituted-N-(2,3-Dihydro-[1,4]benzodioxin-6-yl)-4-acetamidobenzenesulfonamides as valuable antibacterial agents

The aim of the research was to investigate the anti-bacterial potential of some N-substituted sulfonamides bearing benzodioxane moiety. The synthesis was started by reaction of N-2,3-dihydrobenzo[1,4]dioxin-6-amine with 4-acetamidobenzene-1-sulfonyl chloride in the presence of 10% aqueous Na2CO3 solution to yield N-(2,3-dihydrobenzo[1,4]-dioxin-6-yl)-4-acetamidobenzenesulfonamide, which was further reacted with alkyl/aralkyl halides in DMF and lithium hydride as a base to afford N-substituted-N-(2,3dihydro-[1,4]-benzodioxin-6-yl)-4-acetamidobenzenesulfonamides. All the synthesized compounds were characterized by spectral data (IR, 1H NMR, EI-MS, and HR-MS). The compounds were tested for antibacterial activity and most of them exhibited potent therapeutic potential against various Gram-negative and Gram-positive strains.

Cinnamamides, novel liver X receptor antagonists that inhibit ligand-induced lipogenesis and fatty liver

Liver X receptor (LXR) is a member of the nuclear receptor superfamily, and it regulates various biologic processes, including de novo lipogenesis, cholesterol metabolism, and inflammation. Selective inhibition of LXR may aid the treatment of nonalcoholic 1fatty liver diseases. In the present study, we evaluated the effects of three cinnamamide derivatives on ligand-induced LXRalpha activation and explored whether these derivatives could attenuate steatosis in mice. N-(4-trifluoromethylphenyl) 3,4-dimethoxycinnamamide (TFCA) decreased the luciferase activity in LXRE-tk-Luc-transfected cells and also suppressed ligand-induced lipid accumulation and expression of the lipogenic genes in murine hepatocytes. Furthermore, it significantly attenuated hepatic 1neutral lipid accumulation in a ligand-induced fatty liver mouse 1system. Modeling study indicated that TFCA inhibited activation of the LXRalpha ligand-binding domain by hydrogen bonding to Arg305 in the H5 region of that domain. It regulated the transcriptional control exerted by LXRalpha by influencing coregulator exchange; this process involves dissociation of the thyroid hormone receptor-associated proteins (TRAP)/DRIP coactivator and recruitment of the nuclear receptor corepressor. These results show that TFCA has the potential to attenuate ligand-induced lipogenesis and fatty liver by selectively inhibiting LXRalpha in the liver.

A series of 3-(substituted sulfanyl)-4-hydroxy-6-substituted-pyran-2-ones were synthesized for Human immunodeficiency virus-1 protease inhibition. These compounds were synthesized in a simple and convergent fashion to allow us a rapid preparation of many structurally diversified analogues. Thus the condensation of trimethylsilyl enol ethers of corresponding ketones, with 2-(S-substituted)propane-1,3-dioates afforded the corresponding pyrones in 24-70% isolated yields.

Decarboxylative alkynylation and cyanation of carboxylic acids using photoredox catalysis and hypervalent iodine reagents

Alkynes and nitriles are important functional groups that serve as versatile building blocks in organic synthesis and find applications in material and medicinal sciences. A convenient and straightforward access to both classes of compounds under mild conditions is, therefore, highly desirable. Herein, we disclose the decarb-oxylative alkynylation and cyanation of broadly available carboxylic acids using photoredox catalysis and hyper-valent iodine reagents. Choices of both catalysts and reagents were crucial. Computational and experimental studies revealed two different possible mechanisms that are dictated by the oxidation potential of the reagents: radical for alkynylation, ionic for cyanation.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Product Details of 70918-54-6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 70918-54-6, in my other articles.

Mizoroki-heck reactions with 4-phenoldiazonium salts

Significantly better yields were achieved in Mizoroki-Heck reactions using 4-phenoldiazonium salts instead of their O-alkylated analogues under otherwise identical conditions. We found that a one-flask deacetylation-diazotation- precipitation sequence starting from paracetamol or acetanilides derived thereof provides a convenient access to the required diazonium tetrafluoroborates. The utility of these arylating agents in palladium-catalyzed C-C bond forming reactions was demonstrated for a one-flask-synthesis of the heterocyclic core of the drug aripiprazole. Notably, the diazonium salt formation from an acetanilide could be combined with two Pd-catalyzed steps in a one-flask sequence, without any exchange of solvents or isolation of intermediates.

Hypervalent Iodine(III)-Mediated Oxidative Fluorination of Alkylsilanes by Fluoride Ions

The first example of a hypervalent iodine(III)-mediated oxidative fluorination of alkylsilanes by fluoride ions without the use of transition metals is demonstrated. This reaction is operationally simple, scalable, and proceeds under mild reaction conditions. Mechanistic studies suggest the involvement of a single-electron transfer resulting from the interaction of an organopentafluorosilicate and aryliodonium difluoride, which were generated in situ from the corresponding alkylsilane and iodosobenzene, respectively, in the presence of fluoride ions.
