Complex engineering of Solanum alkaloids structural diversity in Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
Summary Transient expression in Nicotiana benthamiana offers a powerful and versatile platform for rapid production of complex specialized metabolites. Steroidal glycoalkaloids (SGAs) and steroidal saponins produced by members of the Solanaceae family are known for their diverse structures and activities including antimicrobial, anticancer, antiviral ...

Genetic predisposition to the metabolism of irinotecan (CPT-11). Role of uridine diphosphate glucuronosyltransferase isoform 1A1 in the glucuronidation of its active metabolite (SN-38) in human liver microsomes.

Journal of Clinical Investigation, 1998
Irinotecan (CPT-11) is a promising antitumor agent, recently approved for use in patients with metastatic colorectal cancer. Its active metabolite, SN-38, is glucuronidated by hepatic uridine diphosphate glucuronosyltransferases (UGTs).

Impact of UGT1A1 gene variants on total bilirubin levels in Gilbert syndrome patients and in healthy subjects [PDF]

, 2012
A significant different allelic distribution, in Gilbert patients and in controls, was found for two promoter polymorphisms. Among patients, 82.2% were homozygous and 17.8% heterozygous for the c.− 41_ − 40dupTA allele; in control group, 9.9% were ...

Unveiling the catalytical roles of three glycosyltransferases in triterpenoid saponins in quinoa

Plant Biotechnology Journal, EarlyView.
Summary Saponins constitute a class of characteristic compounds within quinoa grains. In this study, metabolomic analysis identified 20 triterpene saponins, the majority of which were exclusively localized within the pericarp. Furthermore, three crucial glycosyltransferases were identified in quinoa.

Computer-Aided Identification of Trypanosoma brucei Uridine Diphosphate Galactose 4′-Epimerase Inhibitors: Toward the Development of Novel Therapies for African Sleeping Sickness

Journal of Medicinal Chemistry, 2010
Trypanosoma brucei, the causative agent of human African trypanosomiasis, affects tens of thousands of sub-Saharan Africans. As current therapeutics are inadequate due to toxic side effects, drug resistance, and limited effectiveness, novel therapies are

5'-nucleotidases, nucleosides and their distribution in the brain: pathological and therapeutic implications [PDF]

, 2013
Elements of the nucleoside system (nucleoside levels, 5'-nucleotidases (5'NTs) and other nucleoside metabolic enzymes, nucleoside transporters and nucleoside receptors) are unevenly distributed in the brain, suggesting that nucleosides have region ...

Cysteine Signalling in Plant Pathogen Response

Plant, Cell &Environment, EarlyView.
ABSTRACT The amino acid cysteine is the precursor for a wide range of sulfur‐containing functional molecules in plants, including enzyme cofactors and defence compounds. Due to its redox active thiol group cysteine is highly reactive. Synthesis and degradation pathways are present in several subcellular compartments to adjust the intracellular cysteine

P2Y₂ Nucleotide Receptors Expressed Heterologously in Sympathetic Neurons Inhibit Both N-Type Ca²⁺ and M-Type K⁺ Currents [PDF]

, 1998
The P2Y₂ receptor is a uridine/adenosine triphosphate (UTP/ATP)-sensitive G-protein-linked nucleotide receptor that previously has been reported to stimulate the phosphoinositide signaling pathway.
