t 326

HDAC3-IN-T326 is a potent and selective HDAC3 inhibitor that acts by increasing NF-κB acetylation and activating HIV gene expression in latent HIV-infected cells.

3β-OH-7-Oxocholenic acid is a bile acid.1 It is also a metabolite of 7β-hydroxy cholesterol in rats. Conjugated forms of 3β-OH-7-oxocholenic acid have been found in the urine of patients with Neimann-Pick disease type C.2,3 |1. Norii, T., Yamaga, N., and Yamasaki, K.

Methylatropine is an antagonist of muscarinic acetylcholine receptors (IC50= <0.1 nM in a radioligand binding assay using isolated porcine brain membranes) and a derivative of atropine .1,2It reduces acetylcholine-induced decreases in blood pressure in rats when administered intravenously with an ED50value of 5.5 μg/kg.2Methylatropine reduces salivation, induces mydriasis, and increases heart rate in dogs.3 1.Schmeller, T., Sporer, F., Sauerwein, M., et al.Binding of tropane alkaloids to nicotinic and muscarinic acetylcholine receptorsPharmazie50(7)493-495(1995) 2.Brezenoff, H.E., Xiao, Y.-F., and Vargas, H.A comparison of the central and peripheral antimuscarinic effects of atropine and methylatropine injected systemically and into the cerebral ventriclesLife Sci.42(8)905-911(1988) 3.Albanus, L.Central and peripheral effects of anticholinergic compoundsActa Pharmacol.
