Minimal Fluorous Tagging Strategy that Enables the Synthesis of the Complete Stereoisomer Library of SCH725674 Macrolactones
摘要:
Four mixtures of four fluorous-tagged quasiisomers have been synthesized, demixed, and detagged to make all 16 stereoisomers of the macrocyclic lactone natural product Sch725674. A new bare-minimum tagging pattern needs only two tags one fluorous and one nonfluorous-to encode four isomers. The structure of Sch725674 is assigned as (5R,6S,8R,14R,E)-5,6,8-trihydroxy-14-pentyloxacyclotetradec-3-en-2-one. Various comparisons of spectra of 32 lactones (16 with tags, 16 without) and 16 ester precursors (8 with tags, 8 without) provide insights into when and why related compounds have the same or different spectra.

Compounds of Formula I or stereoisomers, tautomers, or pharmaceutically acceptable salts, solvates or prodrugs thereof, wherein Ring A, Ring C, X, Ra, Rb, Rc, Rd and n are as defined herein, are inhibitors of TrkA kinase and are useful in the treatment of diseases which can be treated with a TrkA kinase inhibitor such as pain, cancer, inflammation/inflammatory diseases, neurodegenerative diseases, certain infectious diseases, Sjogren's syndrome, endometriosis, diabetic peripheral neuropathy, prostatitis or pelvic pain syndrome.
The extension of the solvent influence of the shell into the volume of a polar medium was examined by means of anti‐collinear dipoles on the basis of the ET(30) solvent polarity scale (i.e., the molar energy of excitation of a pyridinium‐N‐phenolatebetaine dye; generally: ET=28 591 nm kcal mol−1/λmax) where no compensation effects were found. As a consequence, solvent polarity effects are concentrated
Steroidal antiandrogens and pharmaceutical compositions thereof, are used for reduction of the risk of developing, or for treatment of, androgen-dependent skin related diseases. In preferred embodiments, the antiandrogen EM-3180 is used for reduction of the risk of developing, or the treatment, of acne, seborrhea, hirsutism or androgenic alopecia: Methods of treatment utilize the antiandrogen alone, or in combination with other active ingredients such as an inhibitor of a 5a-reductase, an inhibitor of type 5 170hydroxysteroid dehydrogenase, and/or an inhibitor of prostate short-chain dehydrogenase/reductase.
