1. TMC-2A, -2B and -2C, new dipeptidyl peptidase IV inhibitors produced by Aspergillus oryzae A374. II. Isolation and structure determination

New dipeptidyl peptidase IV inhibitors, TMC-2A, -2B, and -2C, were isolated from the fermentation broth of Aspergillus oryzae A374. On the basis of chemical, spectroscopic and X-ray crystallographic analyses, their structures were established to be peptide-like compounds composed of three moieties, L-tryptophan, mono- or dihydroxy-L-leucine and highly substituted isoquinoline.
2. TMC-2A, -2B and -2C, novel dipeptidyl peptidase IV inhibitors produced by Aspergillus oryzae A374. I. Taxonomy of producing strain, fermentation, and biochemical properties
N Nonaka, Y Asai, M Nishio, K Takahashi, T Okuda, S Tanaka, T Sugita, T Ohnuki, S Komatsubara J Antibiot (Tokyo). 1997 Aug;50(8):646-52. doi: 10.7164/antibiotics.50.646.
TMC-2A(1), -2B (2) and -2C (3), novel dipeptidyl peptidase IV (DPIV) inhibitors, were isolated from the fermentation broth of Aspergillus oryzae A374. TMC-2A, -2B and -2C inhibited rat kidney DPIV with IC50 value of 8.1 microM, 17 microM, and 20 microM, respectively, as well as human DPIV prepared from mononuclear cells and adenocarcinoma cells. TMC-2 compounds inhibited only DPIV among the proteases tested, indicating their high selectivity for DPIV. The kinetic analyses revealed that TMC-2A was an uncompetitive inhibitor. Taxonomy and fermentation of the producing strain are also described.
