The total synthesis of calcium atorvastatin

A practical and convergent asymmetric route to calcium atorvastatin (1) is reported. The synthesis of calcium atorvastatin (1) was performed using the remote 1,5-anti asymmetric induction in the boron-mediated aldol reaction of beta-alkoxy methylketone (4) with pyrrolic aldehyde (3) as a key step. Calcium atorvastatin was obtained from aldehyde (3) after 6 steps, with a 41% overall yield.

Synthesis of N-(fluoren-9-ylmethoxycarbonyl)glycopyranosylamine uronic acids

The synthesis of 10 N-(fluoren-9-ylmethoxycarbonyl)glycopyranosylamine uronic acids that are amenable to solid-phase synthesis is described. The general synthetic strategy involves initial incorporation of the protected amine, followed by selective TEMPO oxidation of C-6 hydroxyl groups to give the corresponding Fmoc-protected sugar amino acids. Amine incorporation may be accomplished from aminolysis of the free sugar or from glycosyl azide reduction. The reactions can be carried out on multigram scale, providing access to unique monomer units for future incorporation into combinatorial library syntheses.

Synthesis of a glucuronic acid and glucose conjugate library and evaluation of effects on endothelial cell growth

Compounds that alter endothelial cell growth are of interest in the development of angiogenesis modulators. A structurally diverse series of saccharide derivatives (glycosylamide conjugates) have been synthesized and evaluated for their effects on bovine aortic endothelial cell (BAEC) growth. Heparin-albumin (HA) reduced BAEC growth by 32% at 10mug/mL and a number of the novel saccharide conjugates from the library were found to mimic the effect of HA as they also inhibit endothelial cell survival under identical conditions. Two thiophene conjugates, thioglucamide (24% inhibition at 35muM) and a related glucuronide (26% inhibition at 33muM) were the most potent inhibitors of BAEC growth, as determined using a methylthiazol tetrazolium (MTT) assay. The effects of thioglucamide and HA on absolute cell number were also studied using cell counting experiments; thioglucamide (47% after 24h) was more potent than indicated by the MTT assay and initially reduced the BAEC number to a greater extent than HA (30% after 24h); however, its actions were over more rapidly than were HA’s as cell growth had returned to levels of the control after 72h where HA still caused 25% inhibition. The binding of the monosaccharide conjugates to fibroblast growth factor (FGF-2) in competition with heparin-albumin by ELISA was investigated to establish the possible mechanism by which glycoconjugates could alter growth but there was no general correlation between reduction in viable cell population and binding to FGF-2. No glycoconjugate reduced the proliferation of mouse mammary epithelial cells, nor did any alter gross cell morphology, supporting a proposal that the reduction in BAEC survival by monosaccharide conjugates such as thioglucamide is a result of the inhibition of cell proliferation rather than being an induction of cytotoxicity. These studies indicate that cell biological studies to determine the mechanism of action of the simple monosaccharide conjugates may be worthwhile.

The synthesis and evaluation of new benzophenone derivatives as tubulin polymerization inhibitors

Inspired by the potent inhibition activity of phenstatin and millepachine against cancer cell growth, a series of new benzophenone derivatives were synthesized and evaluated as tubulin polymerization inhibitors. Among them, compound 10a exhibited 0.029-0.062 muM of IC50 for five human cancer cell lines, which is much better than that of the two leading compounds. Flow cytometric analysis showed that 10a induces G2/M phase arrest and apoptosis in A549 cells. Cellular studies revealed that the induction of apoptosis by 10a was associated with the collapse of the mitochondrial membrane potential (MMP). Overall, the current study demonstrates that the benzophenone derivatives are promising anticancer agents by targeting tubulin.

Nickel(II) complexes of the non-steroidal anti-inflammatory drug tolfenamic acid: Synthesis, structure, antioxidant activity and interaction with albumins and calf-thymus DNA

The reaction of NiCl2¡¤6H2O with the non-steroidal anti-inflammatory drug tolfenamic acid (Htolf) in the absence or presence of a nitrogen-donor heterocyclic ligand such as 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen), 2,2?-bipyridylamine (bipyam), 2,2?-dipyridylketone oxime (Hpko) and pyridine (py) led to the formation of six novel Ni(II) mononuclear complexes. The complexes were characterized by physicochemical and spectroscopic techniques and the crystal structures of complexes [Ni(tolf-O)2(bipy)(MeOH)2], 2 and [Ni(tolf-O)2(Hpko-N,N?)2], 5 were determined by X-ray crystallography. The in vitro investigation of the ability of the complexes to scavenge 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals and to inhibit soybean lipoxygenase revealed their potential antioxidant activity. The interaction of the complexes to calf-thymus DNA was monitored by diverse techniques (UV spectroscopy, cyclic voltammetry, viscosity measurements) revealing intercalation as the most possible mode of binding. Competitive studies of the complexes with ethidium bromide were monitored by fluorescence emission spectroscopy. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the binding constants of the compounds to the albumins were calculated.

Synthesis, biological evaluation and docking studies of casuarine analogues: Effects of structural modifications at ring B on inhibitory activity towards glucoamylase

We report the total synthesis of a series of pyrrolizidine analogues of casuarine (1) and their 6-O-alpha-glucoside derivatives. The synthetic strategy is based on a totally regio- and stereoselective 1,3-dipolar cycloaddition of suitably substitutedalkenes and a carbohydrate-based nitrone. We also report the evaluation of the biological activity of casuarine and its derivatives towards a wide range of glycosidases and a molecular modeling study focused on glucoamylase (GA) in which the binding modes of the newly synthesized compounds within the enzyme cavity are investigated. The results highlight the prominent structural features of casuarine and its derivatives that make them selective glucoamylase inhibitors. A series of casuarine derivatives structurally modified at ring B of the pyrrolizidine nucleus have been synthesized and found to be selective inhibitors of fungal amyloglucosidase. The nature of the interactions between the enzyme active site and the prepared molecules has been investigated by molecular docking simulations.
