Thymidylat-synthase

WebbThe de novo synthesis of thymidinemonophosphate is blocked by in vitro incubation with fluorodeoxyuridine (FUdR) of erythropoietic bone marrow cells of a normal rat and a healthy individual. The cells maintain a normal DNA synthesis rate under these conditions by increasing the incorporation rate of14C-thymidine out of the medium. Thereby the … WebbWith the aim to identify novel inhibitors of parasitic nematode thymidylate synthase (TS), we screened in silico an in-house library of natural compounds, taking advantage of a model of nematode TS three-dimensional (3D) structure and choosing candidate compounds potentially capable of enzyme binding/inhibition. Selected compounds were …
