  Total synthesis of a second generation HIV protease inhibitor

  摘要：

  An efficient stereoselective preparation of HIV protease inhibitor (+)-1 was synthesized on multi-kilogram scale in 16 steps without the use of chromatography. The key steps include the diastereoselective alkylation of acetal 3, a diastereoselective iodo-hydroxylation to generate epoxide 6, and a reductive amination in the final coupling step that averts a non-productive Cyclic aminal intermediate.

  Synthesis of 5-Pyridyl-2-furaldehydes via Palladium-Catalyzed Cross-Coupling with Triorganozincates

  摘要：

  [GRAPHICS]-Pyridyl- and 5-aryl-2-furaidehydes are prepared from furaldehyde diethyl acetal in a four-step, one-pot procedure: (1) deprotonation; (2) U to Zn transmetalation; (3) Pd-medlated cross-coupling; (4) aldehyde deprotection. Triorganozincate 7 was found to transfer all three groups in the Pd-catalyzed cross-coupling reaction with haloaromatics.

  &ggr;-Hydroxy-2-(fluoroalkylaminocarbonyl)-1-piperazinepentanamide compounds are inhibitors of HIV protease and inhibitors of HIV replication. These compounds are useful in the prevention or treatment of infection by HV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described. These compounds are effective against HIV viral mutants which are resistant to HIV protease inhibitors currently used for treating AIDS and HIV infection.

  PRMT5 is an important protein arginine methyltransferase that catalyzes the symmetric dimethylation of arginine resides on histones or non-histone substrate proteins. It has been thought as a promising target for many diseases, particularly cancer. Despite the potential applications of PRMT5 inhibitors in cancer treatment, very few of PRMT5i have been publicly reported. In this investigation, virtual

  PRMT5是一种重要的蛋白质精氨酸甲基转移酶，可催化组蛋白或非组蛋白底物蛋白质上的精氨酸对称二甲基化。人们认为它是许多疾病，特别是癌症的有希望的靶标。尽管PRMT5抑制剂在癌症治疗中有潜在的应用，但PRMT5i很少公开报道。在这项调查中，进行了虚拟筛选和结构-活性关系（SAR）研究，以发现新型PRMT5i，最终导致鉴定出许多新的PRMT5i。最具活性的化合物P5i-6对PRMT5表现出相当大的抑制效能，IC50值为0.57μM，对PRMT5对其他测试PRMT的选择性也很高。它对两种结直肠癌细胞系显示出非常好的抗活力，HT-29和DLD-1，以及一种肝癌细胞系HepG2，针对36种不同的癌细胞系进行了敏感性分析。Western Blot分析表明，P5i-6选择性抑制DLD-1细胞中H4R3和H3R8的对称二甲基化。总体而言，P5i-6可以用作化学探针，以研究PRMT​​5在生物学中的新功能，
