  Benzoquinazoline inhibitors of thymidylate synthase: enzyme inhibitory activity and cytotoxicity of some 3-amino- and 3-methylbenzo[f]quinazolin-1(2H)-ones

  摘要：

  The synthesis and thymidylate synthase (TS) inhibitory activity of a series of simple benzo-[f]-quinazolin-1(2H)-ones are described. Fully aromatic 3-amino compounds with compact lipophilic substituents in the 9-position were found to have I50 values as low as 20 nM on the isolated enzyme, and represent the first examples of potent, folate-based TS inhibitors that completely lack any structural feature corresponding to the (p-aminobenzoyl)glutamate moiety of the cofactor. A number of the compounds also showed moderate growth inhibitory activity against a human colon adenocarcinoma cell line (SW480), with IC50 values as low as 2 muM.

  A method for the synthesis of 2-naphthols 4 is described. The carbonylative Stille coupling reactions of 2-bromobenzyl bromides with tributylallylstannane to produce 2-bromobenzyl β,γ-unsaturated ketones 2 in satisfactory to excellent yields has been achieved. The isomerization of 2-bromobenzyl β,γ-unsaturated ketones 2 can readily occur under basic conditions to generate 2-bromobenzyl α,β-unsaturated

  Chemists devote tremendous effort to the precise placement of oxygens in molecular frameworks. Wu et al . report a convenient method to shift the oxygen in a carbonyl group to an adjacent carbon center. After activation of the oxygen to an alkenyl triflate, cooperative catalysis by palladium and norbornene adds nitrogen to the neighboring carbon while displacing the triflate with hydride. Hydrolysis then produces the desired shifted ketone. The protocol is well suited to late-stage variation of complex molecules during drug optimization. —JSY

  标题：酮转移的谨慎编排 化学家们致力于在分子框架中精确放置氧原子。吴等人报告了一种方便的方法，将羰基中的氧转移到相邻的碳中心。在将氧活化为烯基三氟乙酸酯后，钯和环辛烯的协同催化作用在邻近碳上加入氮，同时用氢化物取代三氟乙酸酯。然后水解产生所需的转移酮。该协议非常适合在药物优化期间对复杂分子进行后期变异。 —JSY

  Compounds, methods of use, and processes for making inhibitors of complement factor D comprising Formula I, or a pharmaceutically acceptable salt or composition thereof wherein R 12 or R 13 on the A group is an ether (R 32 ) are provided. The inhibitors described herein target factor D and inhibit or regulate the complement cascade at an early and essential point in the alternative complement pathway, and reduce factor D's ability to modulate the classical and lectin complement pathways. The inhibitors of factor D described herein are capable of reducing the excessive activation of complement, which has been linked to certain autoimmune, inflammatory, and neurodegenerative diseases, as well as ischemia-reperfusion injury and cancer.

  A new method for the preparation of 4-alkyl-β-tetralones is described, by reaction of arylacetic acid chlorides with allylsilanes. Employing β-tetralone 5, the synthesis of (±)-heritonine and (±)-epi-heritonine, natural piscicides isolated from Heritiera littoralis, was achieved in four steps and 22% overall yield. The key step of this synthesis involved the selenocarbenium ion-mediated elaboration

  4-Aryl-2-hydroxybutanal diethyl acetal, prepared from the reaction of benzyl Grignard reagent and glycidaldehyde diethyl acetal, was treated with titanium tetrachloride to give 2-tetralone in good yield. This highly efficient transformation involves tandem oxonium formation, intramolecular Friedel–Crafts alkylation, deethoxylation, and tautomerization in the same flask.
