First human administration of MR04A3: a novel water-soluble nonbenzodiazepine sedative.

Background: JM-1232(-), (-)-3-[2-(4-methyl-1-piperazinyl)-2-oxoethyl]-2-phenyl-3,5,6,7-tetrahydrocyclopenta [f]isoindol-1(2H)-one, molecular formula, C(24)H(27)N(3)O(2); molecular weight, 389.49, is a novel isoindoline water-soluble benzodiazepine receptor agonist with favorable anesthetic/sedative properties in animals. MR04A3 is a 1% aqueous presentation of JM-1232(-).

First administration to man of Org 25435, an intravenous anaesthetic: A Phase 1 Clinical Trial.

Background: Org 25435 is a new water-soluble alpha-amino acid ester intravenous anaesthetic which proved satisfactory in animal studies. This study aimed to assess the safety, tolerability and efficacy of Org 25435 and to obtain preliminary pharmacodynamic and pharmacokinetic data.

Methods: In the Short Infusion study 8 healthy male volunteers received a 1 minute infusion of 0.

Phase I clinical studies of the advanced glycation end-product (AGE)-breaker TRC4186: safety, tolerability and pharmacokinetics in healthy subjects.

Background And Objective: Advanced glycation end-products (AGEs) have been implicated in the pathogenesis of diabetic complications through a variety of mechanisms including endothelial dysfunction and structural abnormalities in the vasculature and myocardium. Reducing the AGEs burden and their ensuing pro-inflammatory, pro-oxidative and pro-coagulant effect with associated dysfunctional proteins in various target tissues may retard the progression of and even reverse diabetic macro- and microvascular complications. Pyridinium, 3-[[2-(methylsulfonyl) hydrazino] carbonyl]-1-[2-oxo-2-2-thienyl) ethyl]-chloride (TRC4186) has demonstrated AGE-breaking activities in in vitro experiments and improvement in the endothelial and myocardial function in animal models of diabetes mellitus with reduction of AGEs accumulation in tissues over time.
