Bonilla-Reyes, Edgar,Sánchez-Carrillo, Adrian,Vázquez, Alfredo
, p. 3473 - 3479 (2020/09/15)
l -Kynurenine, a non-proteinogenic amino acid, is the primary metabolite of tryptophan via the kynurenine pathway. Kynurenine is involved in a variety of biological processes occurring in the human body, notably in the central nervous system. Thus, the st

Three N-Boc-protected amino acids, l-serine, l-aspartic, and l-glutamic acid, were either converted into their methyl azidoalkanoates or various alkynes via Bestmann-Ohira strategy or via reaction with propargylamine and propargyl bromide, respectively. The Cu-catalyzed click reaction provided a library of amino acid based triazoles, which were further N-methylated to triazolium iodides or deprotected and precipitated as free amino acid triazole dihydrochlorides. The biological properties of all derivatives were investigated by cytotoxicity assay (against L929 mouse fibroblasts) and broth microdilution method (E. coli ΔTolC and S. aureus). First results reveal complete inactivity for triazolium iodides with cell viabilities and microbial growths nearly 100 %, indicating them as possible analogs of advanced glycation endproducts (AGEs).

Pin1 (protein interacting with never in mitosis A-1) is a member of the peptidyl prolyl isomerase (PPIase) family, and catalyzes cis-trans isomerization of pThr/Ser-Pro amide bonds. Because Pin1 is overexpressed in various cancer cell lines and promotes c
Thaxtomin A and its stereoisomers of the synthesis method
-
Paragraph 0008; 0035-0036, (2018/06/19)
The invention relates to Thaxtomin A and a synthesis method of a stereisomer of Thaxtomin A. The chemical constructions of Thaxtomin A and the stereisomer are as shown in the specification. The invention further provides a synthesis method of the stereisomer. The synthesis route has the characteristics of being efficient, and the stereisomer can be spliced by recrystallization, which is beneficial to mass production of target products.
Synthesis of rhodotorulic acid and its 1,4-dimethylated derivative
Nakao, Michiyasu,Fukayama, Shintaro,Kitaike, Syuji,Sano, Shigeki
, p. 1309 - 1316 (2015/03/04)
Facile syntheses of rhodotorulic acid, isolated from Rhodotorula pilimanae as a siderophore, and its 1,4-dimethylated derivative have been achieved by microwave-assisted cyclization of the corresponding dipeptide precursors.
Synthesis of triazole cages containing C3-symmetric α-cyclic tripeptide scaffold
Chakraborty, Subrata,Tai, Dar-Fu
supporting information, p. 2274 - 2276 (2014/04/17)
Two water-soluble C3-symmetric 1,2,3-triazole cages containing α-cyclic tripeptide were efficiently synthesized. The key steps include a click reaction to incorporate l-glutamic or l-aspartic acids to a tripodal linker and a unique one-pot cyclotrimerization.

Page/Page column 41-42, (2009/01/24)
Disclosed are compounds having polybasic functionalities. The compounds inhibit bacterial efflux pump inhibitors and are used in combination with an anti-bacterial agent to treat or prevent bacterial infections. These combinations can be effective against bacterial infections that have developed resistance to anti-bacterial agents through an efflux pump mechanism.
Ruthenium tetroxide oxidation of cyclic N-acylamines by a single layer method: formation of ω-amino acids
Kaname, Mamoru,Yoshifuji, Shigeyuki,Sashida, Haruki
, p. 2786 - 2788 (2008/09/19)
The ruthenium tetroxide oxidation of cyclic N-acyl amines by a 10% NaIO4 aqueous solution containing tert-butanol as a single layer system resulted in the endo-cyclic C-N bond cleavage to afford the ω-amino acids as almost sole products in good yields, while a similar oxidation under the double layer using a NaIO4 aqueous solution, and ethyl acetate gave the N-acyl lactams.
