Blebbistatin reduces calcium buffering in cardiomyocytes: Consequences for cellular electrophysiology

The Journal of Physiology, Volume 604, Issue 16, Page 6858-6871, 15 August 2026.
Abstract figure legend Blebbistatin reduces Ca2+ buffering in induced pluripotent stem cell‐derived atrial cardiomyocytes. Blebbistatin, a widely used excitation–contraction uncoupling agent, decreases calcium (Ca2+) buffer affinity (increased buffer dissociation constant), leading to elevated diastolic Ca2+ levels, increased sarcoplasmic reticulum Ca2+

Influence of N‐Functionalization of Amiridine on the Biological Activity of Its Conjugates as Multitarget Agents for Potential Treatment of Alzheimer's Disease

ChemMedChem, Volume 21, Issue 14, 29 July 2026.
New conjugates of amiridine and salicylimine/amine with an N‐acylalkylene spacer were synthesized. N‐acylation of amiridine conjugates leads to a decrease in their protonation, resulting in a substantial reduction in anticholinesterase activity and relative inability to block Aβ42 self‐aggregation compared to previously studied analogs with an N ...

Suppression of Inflammatory Demyelinaton and Axon Degeneration through Inhibiting Kv3 Channels

Frontiers in Molecular Neuroscience, 2017
The development of neuroprotective and repair strategies for treating progressive multiple sclerosis (MS) requires new insights into axonal injury. 4-aminopyridine (4-AP), a blocker of voltage-gated K+ (Kv) channels, is used in symptomatic treatment of ...

Potentiation of neostigmine and pyridostigmine by 4-aminopyridine in the rat

Journal of Pharmacy and Pharmacology, 1978
AbstractThe interaction between 4-aminopyridine and neostigmine or pyridostigmine was studied in vivo in the rat sciatic nerve-anterior tibialis preparation using the constant infusion of pancuronium technique. The ED50 (dose of drug which produced a 50% antagonism) of neostigmine, pyridostigmine and 4-aminopyridine were 18, 49 and 440 μg kg−1 ...

Synthesis, Characterization and Antibacterial Properties of Complex [Ag(SCN)(2-NH2py)] [PDF]

E3S Web of Conferences
The reaction of AgSCN with 2-aminopyridine in ammonia solution produces the colorless crystal of catena-poly [Ag(SCN))(C6H5N2)]n. The crystals were characterized by FTIR analysis and single crystal X-Ray diffraction.
