Glycosylation reactions mediated by hypervalent iodine: application to the synthesis of nucleosides and carbohydrates

Beilstein Journal of Organic Chemistry, 2018
To synthesize nucleoside and oligosaccharide derivatives, we often use a glycosylation reaction to form a glycoside bond. Coupling reactions between a nucleobase and a sugar donor in the former case, and the reaction between an acceptor and a sugar donor

Structural Probing and Molecular Modeling of the A3 Adenosine Receptor: A Focus on Agonist Binding

Molecules, 2017
Adenosine is an endogenous modulator exerting its functions through the activation of four adenosine receptor (AR) subtypes, termed A1, A2A, A2B and A3, which belong to the G protein-coupled receptor (GPCR) superfamily.

Effect of developmental changes on pharmacokinetics of drugs used in the treatment of infant acute lymphoblastic leukaemia—A comprehensive review

British Journal of Clinical Pharmacology, EarlyView.
While the event‐free survival (EFS) of children treated for acute lymphoblastic leukaemia (ALL) has improved greatly in the last decades, the EFS for patients diagnosed with ALL before the age of one is still under 50%. This outcome further decreases when infants have a rearrangement in the gene encoding histone‐lysine N‐methyltransferase 2A (KMT2A ...

PrEP at the site of action in cisgender and transgender women: A pharmacology study of blood and rectal CD4+ lymphocytes

British Journal of Clinical Pharmacology, EarlyView.
Background Female sex hormones used in feminizing hormone therapy (FHT) may influence activation and persistence of HIV pre‐exposure prophylaxis (PrEP) medications. The clinical relevance of this interaction remains unclear, particularly for transgender and cisgender women (TGW and CGW).

Pharmacogenomic profiling of the efficacy of gemcitabine monotherapy in metastatic pancreatic cancer: Subgroup analysis of the GENESECT study

British Journal of Clinical Pharmacology, EarlyView.
Aim In the GENESECT study, no significant gemcitabine (GEM) metabolism‐related germline genetic polymorphisms (GPs) were identified because approximately 70% of patients received combination therapy with nab‐paclitaxel, which has metabolic pathways different from GEM.

Nicotinamide Reverses the Warburg Effect in CHO Cell Culture

Biotechnology and Bioengineering, EarlyView.
Abstract The Warburg effect, the preferential conversion of glucose‐derived pyruvat to lactate despite available oxygen, is a key feature of Chinese hamster ovary (CHO) cell culture. Lactate accumulation in recombinant protein‐producing cell culture is an inefficient usage of glucose, as well as being deleterious to cells.

Love Acoustic Wave-Based Devices and Molecularly-Imprinted Polymers as Versatile Sensors for Electronic Nose or Tongue for Cancer Monitoring

Sensors, 2016
Cancer is a leading cause of death worldwide and actual analytical techniques are restrictive in detecting it. Thus, there is still a challenge, as well as a need, for the development of quantitative non-invasive tools for the diagnosis of cancers and ...
