In this report the optimization of biosynthesis of tacrolimus, the immunosupressant widely used in transplantology and dermatology was described. The enhancement of the productivity of Streptomyces tsukubaensis strain was achieved by development of new precursors of tacrolimus biosynthesis, which should

In this study we investigated the effects of picolinic acid, a catabolite of L-tryptophan, on the production of L-arginine-derived reactive nitrogen intermediates in the murine macrophage cell line ANA-1. ANA-1 macrophages did not produce nitrite (NO2-) constitutively, but accumulated detectable

Recent studies have suggested a role for aminoacid catabolites as important regulators of macrophage (Mphi) activities. We reported previously that picolinic acid (PA), a tryptophan catabolite produced under inflammatory conditions and a costimulus with IFNgamma of Mphi effector functions, is

It has been suggested that picolinic acid (PIC), an endogenous metabolite of l-tryptophan, possesses neuro-protective and anti-proliferative effects within the CNS. However, the literature surrounding PIC is limited, and its exact endogenous function is not known. Picolinic acid is produced
