Total synthesis of cryptophycins. Revision of the structures of cryptophycins A and C

The convergent total synthesis of cryptophycins C and D is described. It has been shown that in both natural products the absolute configuration of the alpha-amino acid corresponds to the D-series. The structural assignment for cryptophycin C has been corrected to reflect this fact. Since the structure of cryptophycin A has been correlated to cryptophycin C, the chloro-O-methyltyrosine unit in cryptophycin A has the D-configuration.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 3,4-Di(1H-indol-3-yl)-1H-pyrrole-2,5-dione, you can also check out more blogs about119139-23-0

A diastereoselective construction of pyrazinoisoquinoline skeletons via tandem cyclization of phenylalanine derivatives: A facile synthesis of optically active pyrazinoisoquinolines

A facile and stereocontrolled construction of optically active pyrazinoisoquinoline skeletons based on tandem cyclization of enantiopure phenylalanine derivatives was examined. The reaction provided optically active 6,11b-trans pyrazinoisoquinoline ring systems in excellent diastereoselectivity, and this method was applicable to the cyclization of phenylalanine derivatives with diverse substituents.

Synthesis of new (-)-bestatin-based inhibitor libraries reveals a novel binding mode in the S1 pocket of the essential malaria M1 metalloaminopeptidase

The malarial PfA-M1 metallo-aminopeptidase is considered a putative drug target. The natural product dipeptide mimetic, bestatin, is a potent inhibitor of PfA-M1. Herein we present a new, efficient, and high-yielding protocol for the synthesis of bestatin derivatives from natural and unnatural N-Boc-d-amino acids. A diverse library of bestatin derivatives was synthesized with variants at the side chain of either the alpha-hydroxybeta-amino acid (P1) or the adjacent naturalalpha-amino acid (P1?). Surprisingly, we found that extended aromatic side chains at the P1 position resulted in potent inhibition against PfA-M1. To understand these data, we determined the X-ray cocrystal structures of PfA-M1 with two derivatives having either a Tyr(OMe) 15 or Tyr(OBzl) 16 at the P1 position and observed substantial inhibitor-induced rearrangement of the primary loop within the PfA-M1 pocket that interacts with the P1 side chain. Our data provide important insights for the rational design of more potent and selective inhibitors of this enzyme that may eventually lead to new therapies for malaria.
