-
Paragraph 0027-0029, (2019/12/25)
The invention provides a preparation method of amoxicillin. The amoxicillin is obtained by synthesis of amino protected raw materials, the reaction route is short, product purity is high, operation iseasy, and wide industrial application prospects are achieved.
Discovery of Nanomolar Dengue and West Nile Virus Protease Inhibitors Containing a 4-Benzyloxyphenylglycine Residue

The dengue virus (DENV) and West Nile Virus (WNV) NS2B-NS3 proteases are attractive targets for the development of dual-acting therapeutics against these arboviral pathogens. We present the synthesis and extensive biological evaluation of inhibitors that
A facile Fmoc solid phase synthesis strategy to access epimerization-prone biosynthetic intermediates of glycopeptide antibiotics
Brieke, Clara,Cryle, Max J.
supporting information, p. 2454 - 2457 (2014/05/20)
A rapid protocol based on Fmoc-chemistry for the solid phase peptide synthesis of vancomycin- and teicoplanin-type peptides is described. Epimerization of highly racemization-prone arlyglycine derivatives is suppressed through optimized Fmoc-deprotection

Philanthotoxin-343 (PhTX-343), a synthetic analogue of wasp toxin PhTX-433, is a noncompetitive antagonist at ionotropic receptors (e.g., AChR or iGluR). To determine possible effects of variations of the amino acid side chain, a library consisting of seventeen PhTX-343 analogues was prepared. Thus, tyrosine was replaced by either apolar, conformationally constrained, or bulky amino acids, whereas the acyl unit and the polyamine moiety were kept unchanged. Analogues with tertiary amide groups were prepared for the first time. Pentafluorophenyl esters were employed for amide bond formation, establishing general protocols for philanthotoxin solution- and solid-phase synthesis (39-90% and 42-54% overall yields, respectively). The analogues were tested for their ability to antagonize kainate-induced currents of 2-amino-3-(3-hydroxy-5-methyl- 4-isoxazoyl)propanoic acid receptors (AMPAR) expressed in Xenopus oocytes from rat brain mRNA. This showed that steric bulk in the amino acid moiety is well tolerated and suggests that binding to AMPAR does not involve the α-NHCO group as a donor in hydrogen bonding.
