  Coordination Chemistry Based Approach to Lipophilic Inhibitors of 1-Deoxy-d-xylulose-5-phosphate Reductoisomerase

  摘要：

  1-Deoxy-D-xylulose-5-phosphate reductoisomerase (DXR) in the non-mevalonate pathway found in most bacteria is a validated anti-infective drug target. Fosmidomycin, a potent DXR inhibitor, is active against Gram-negative bacteria. A coordination chemistry and structure based approach was used to discover a novel, lipophilic DXR inhibitor with an IC50 of 1.4 mu M. It exhibited a broad spectrum of activity against Gram-negative and -positive bacteria with minimal inhibition concentrations of 20-100 mu M (or 3.7-19 mu g/mL).

  Synthesis and Biological Evaluation of N-[2-(4-Hydroxyphenylamino)-pyridin-3-yl]-4-methoxy-benzenesulfonamide (ABT-751) Tricyclic Analogues as Antimitotic and Antivascular Agents with Potent in Vivo Antitumor Activity

  摘要：

  Benzopyridothiadiazepine (2a) and benzopyridooxathiazepine (2b) were modified to produce tricyclic quinazolinone 15-18 or benzothiadiazine 26-27 derivatives. These compounds were evaluated in cytotoxicity and tubulin inhibition assays and led to potent inhibitors of tubulin polymerization. N-[2(4-Methoxyphenyl)ethyl]-1,2-dihydro-pyrimidino[2,1-b]quinazolin-6-one (16a) exhibited the best in vitro cytotoxic activity (GI50 10-66.9 nM) against the NCI 60 human tumor cell line and significant potency against tubulin assembly (IC50 0.812 mu M). In mechanism studies, 16a was shown to block cell cycle in G2/M phase and to disrupt microtubule formation and displayed good antivascular properties as inhibition of cell migration, invasion, and endothelial tube formation. Compound 16a was evaluated in C57BL/6 mouse melanoma B16F10 xenograft model to validate its antitumor activity, in comparison with reference ABT-751 (1). Compound 16a displayed strong in vivo antitumor and antivascular activities at a dose of 5 mg/kg without obvious toxicity, whereas 1 needed a 10-fold higher concentration to reach similar effects.

  An enantioselective route towards the synthesis of C-1 substituted tetrahydroisoquinoline natural products is reported. Six different natural products are synthesized from a single aldehyde using proline-catalyzed asymmetric α-hydrazination reaction as the key step. The highly enantioselective introduction of an amino group is exploited to synthesize (−)-calycotomine, (−)-salsolidine, (−)-carnegine

  The present invention relates to novel bio-inspired hybrid compounds of formula I which act as proteasome activators and exhibit anti-ageing activity, as well as methods for their synthesis. These hybrid compounds combine the structural features of hydroxytyrosol and the natural antioxidant vitamin E or its bioisosteres in one molecular scaffold. The compounds of formula I, which include structural proteasome activators (activation by stereochemical interaction), can be used in the production of anti-ageing products, such as cosmetic preparations. Additionally, they can be used in conditions and diseases where the proteasome is down-regulated, as well as proteasome-activation control compounds.
