Synthesis and in vitro cytotoxicity of hexacyclic Camptothecin analogues

A series of C(7)-N-alkylaminoethyl-C(10), C(11)-methylenedioxy- and ethylenedioxy-camptothecin (3a-g, 4a-h) were prepared. Their syntheses and in vitro cytotoxicity were reported. Among 15 derivatives, 3a and 3b showed more potent cytotoxicity than Camptothecin, especially in CAOV-3 cell line.

Iron-Catalyzed Borrowing Hydrogen beta- C(sp3)-Methylation of Alcohols

Herein we report the iron-catalyzed beta-C(sp3)-methylation of primary alcohols using methanol as a C1 building block. This borrowing hydrogen approach employs a well-defined bench-stable (cyclopentadienone)iron(0) carbonyl complex as precatalyst (5 mol %) and enables a diverse selection of substituted 2-arylethanols to undergo beta-C(sp3)-methylation in good isolated yields (24 examples, 65% average yield).

Kinetics and Mechanism of the Arase-Hoshi R2BH-Catalyzed Alkyne Hydroboration: Alkenylboronate Generation via B-H/C-B Metathesis

The mechanism of R2BH-catalyzed hydroboration of alkynes by 1,3,2-dioxaborolanes has been investigated by in situ 19F NMR spectroscopy, kinetic simulation, isotope entrainment, single-turnover labeling (10B/2H), and density functional theory (DFT) calculations. For the Cy2BH-catalyzed hydroboration 4-fluorophenylacetylene by pinacolborane, the resting state is the anti-Markovnikov addition product ArCH = CHBCy2. Irreversible and turnover-rate limiting reaction with pinacolborane (k ? 7 ¡Á 10-3 M-1 s-1) regenerates Cy2BH and releases E-Ar-CH?CHBpin. Two irreversible events proceed in concert with turnover. The first is a Markovnikov hydroboration leading to regioisomeric Ar-C(Bpin)?CH2. This is unreactive to pinacolborane at ambient temperature, resulting in catalyst inhibition every ?102 turnovers. The second is hydroboration of the alkenylboronate to give ArCH2CH(BCy2)Bpin, again leading to catalyst inhibition. 9-BBN behaves analogously to Cy2BH, but with higher anti-Markovnikov selectivity, a lower barrier to secondary hydroboration, and overall lower efficiency. The key process for turnover is B-H/C-B metathesis, proceeding by stereospecific transfer of the E-alkenyl group within a transient, mu-B-H-B bridged, 2-electron-3-center bonded B-C-B intermediate.

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.

Synthesis, characterization and biological screening of some new sulfonamides derivatives of 1,4-benzodioxane-6-amine

In the present study, a series of N-substituted derivatives of 1,4-benzodioxane-6-amine have been synthesized. The reaction of 1,4-benzodioxane-6-amine (1) with various alkyl/aryl sulfonyl chlorides (2a-k) yielded N-alkyl/aryl sulfonamides (3a-k), which further on treatment with benzyl chloride (4) in the presence of sodium hydride furnished into N-benzylated sulfonamides (6a-k) while the reaction of 3a-k with ethyl iodide (5 ) yielded N-ethylated sulfonamides 7a-k. These derivatives were characterized by IR, 1H-NMR and EI-MS and then screened against acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and lipoxygenase (LOX) enzymes and were found to be good inhibitors of lipoxygenase only. The interaction between inhibitors and target enzymes were computationally observed which correlates with the experimental results.
