Computational quantum chemistry, molecular docking, and ADMET predictions of imidazole alkaloids of Pilocarpus microphyllus with schistosomicidal properties.

PLoS ONE, 2018
Schistosomiasis affects million people and its control is widely dependent on a single drug, praziquantel. Computational chemistry has led to the development of new tools that predict molecular properties related to pharmacological potential.

Pediococcus acidilactici GR-5 alleviates hyperuricemia by degrading purine nucleosides and improving gut microbiota metabolism

npj Science of Food
Reducing intestinal absorption by degrading purine nucleosides has been shown to alleviate hyperuricemia (HUA). The probiotic Pediococcus acidilactici GR-5, derived from the traditional food “Jiangshui”, achieved efficient degradation of purine ...

Identification of aspartic acid-203 in human thymidine phosphorylase as an important residue for both catalysis and non-competitive inhibition by the small molecule "crystallization chaperone" 5'-O-tritylinosine (KIN59) [PDF]

, 2009
Thymidine phosphorylase (TP) is a catabolic enzyme in thymidine metabolism that is frequently upregulated in many solid tumors. Elevated TP levels are associated with tumor angiogenesis, metastasis and poor prognosis.

Efficient whole-cell biocatalytic synthesis of 2′-deoxy-2′-fluoroadenosine, a key building block for nucleic acid drugs

Synthetic and Systems Biotechnology
2′-Deoxy-2′-fluoroadenosine (2′-F-dA) is a nucleoside analogue used as a key building block for oligonucleotide drugs. It can be biosynthesized from a low-cost 2′-deoxy-2′-fluorouridine via one-pot transglycosylation catalyzed by a thymidine ...
