Synthesis and evaluation of dialkyl-4-substituted-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate derivatives as anticonvulsive agents

open access: yesInternational Journal of Research in Pharmaceutical Sciences, 2012
A series of symmetrical dialkyl-4-substituted-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylates were prepared by the classical Hantzsch method. This method involved condensation of aromatic aldehyde, alkylacetoacetate and ammonia in methanol.

Anticancer Activity of 4-Aryl-1,4-Dihydropyridines

open access: yesFuture Pharmacology
We have synthesized 22 symmetric and asymmetric 4-aryl-1,4-dihydropyridines (1,4-DHPs) by a “green” microwave-assisted one-pot multicomponent Hantzsch reaction and evaluated their cytotoxicity to three human cancer cell lines regarding U-251MG (human ...

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Cancer co‐medication quality in older patients with polypharmacy: A large randomized trial testing a medication review versus usual care

open access: yesJournal of Internal Medicine, Volume 300, Issue 6, Page 802-820, December 2026.
Abstract Background Evidence from randomized controlled trials (RCTs) testing medication reviews in geriatric oncology is sparse. Methods We conducted a single‐blinded RCT in ten rehabilitation clinics across Germany. Patients with common cancers, aged ≥ 65 years, and polypharmacy (regularly ≥ five drugs) were randomly allocated in equal proportions to
