N-(3-(4-Hydroxyphenyl)-propenoyl)-amino acid tryptamides as SIRT2 inhibitors
摘要:
A series of N-(3-(4-hydroxyphenyl)-propenoyl)-amino acid tryptamides was based on a previously reported new SIRT2 inhibitor from our group, and it was designed to study if the molecular size of the compound could be reduced. The most potent compounds, N-(3-(4-hydroxyphenyl)-propenoyl)-2-aminoisobutyric acid tryptamide and N-(3-(4-hydroxyphenyl)-propenoyl)-L-alanine tryptamide, were equipotent, 30% smaller in molecular weight, and slightly more selective (SIRT2/SIRT1) than the parent compound.

Naturallyoccurring spider toxins are potent inhibitors of glutamate receptors of the central nervous system and have the general structure (hetero)arylacylaminoacyl(I)polyamineaminoacyl(II) (the arrow indicates the direction of an amide linkage). In the present paper, the synthesis of the ten spider-toxin analogues 13, 18, 21, 28, 35, 37, 39, 41, 45, and 53 are reported (Schemes 1–12). These compounds

Amidation of unprotected aminoacids has been investigated using a variety of ‘classical“ coupling reagents, stoichiometric or catalytic group(IV) metal salts, and boron Lewis acids. The scope of the reaction was explored through the attempted synthesis of amides derived from twenty natural, and several unnatural, aminoacids, as well as a wide selection of primary and secondary amines. The study also
