Tryptophan participates in important life activities and is involved in various metabolic processes. The indole and aromatic binuclear ring structure in tryptophan can engage in diverse interactions, including π-π, π-alkyl, hydrogen bonding, cation-π, and CH-π interactions with other side chains and protein targets. These interactions offer extensive opportunities for drug development.

4'-Selective alkylation of nucleosides has been recognized as one of the ideal and straightforward approaches to chemically modified nucleosides, but such a transformation has been scarce and less explored. In this Letter, we combine a visible-light-mediated photoredox catalysis and hydrogen atom transfer (HAT) auxiliary to achieve β-C(sp)-H alkylation of alcohol on tetrahydrofurfuryl alcohol scaffolds and exploit it for 4'-selective alkylation of nucleosides. The reaction involves an intramolecular 1,5-HAT process and stereocontrolled Giese addition of the resultant radicals.

VTRNA2-1 is a polymorphically imprinted locus. The proportion of individuals with a maternally imprinted VTRNA2-1 locus is consistently approximately 75% in populations of European origin, with the remaining circa 25% having a non-methylated VTRNA2-1 locus. Recently, VTRNA2-1 hypermethylation at birth was suggested to be a precursor of paediatric acute lymphoblastic leukaemia with biomarker potential.

Brentuximab vedotin (BV)-bendamustine (90 or 120 mg/m2 day 1 and 2) every 28 days is an effective treatment for relapsed/refractory Hodgkin lymphoma (R/R HL) but associated to high toxicity especially for elderly patients. We conducted in St Louis Hospital, Paris, between 2015 and 2021 a retrospective single-center analysis of 44 patients with R/R HL treated with one-day BV-bendamustine (120 mg/m2) every 21 days. Sixteen percent of patients were ≥ 60 years old (yo).

Background: Gui-Ling-Ji (GLJ) described in the ancient medical book 'Yunji Qijian' is a traditional Chinese medicine formula used to improve male fertility. It is now available for the treatment of oligoasthenoteratozoospermia (OAT). However, the active ingredients and mechanism of GLJ are not clear.
