Preclinical Pharmacology of GW280430A (AV430A) in the Rhesus Monkey and in the Cat

Abstract: These experiments show a much shorter neuromuscular blocking effect and much-reduced side effects in the case of GW280430A vis-à-vis mivacurium. These results, together with the novel chemical degradation of GW280430A, suggest further evaluation in human subjects.

“…In laboratory animals the reversal is easily obtained with the injection of cysteine 11 , and in human beings it has been accelerated by the use of edrophonium 12 . In experiments in animals and in men the injection of the drug showed little side effects in doses up to 3 times the DE95 13,14 . The presence of a discrete increase in cardiac frequency and reduction of the mean arterial blood pressure was only observed with doses higher than 5 times the DE95 7,14 .…”

“…Em animais de laboratório, a reversão é obtida com facilidade com a injeção de cisteína 11 e em seres humanos foi acelerada com o uso de edrofônio 12 . Em experimentação animal e no homem, a injeção da droga mostrou insignificantes efeitos colaterais em doses até três vezes a DE95 13,14 . A presença de discreto aumento da freqüência cardíaca e diminuição da pressão arterial média foi observada somente com doses superiores a cinco vezes a DE95 7,14 .…”

“…1) [12]. Subsequent invitro investigation revealed this interaction to be relatively fast (reaction half-time of $15 s) and to yield an adduction product with very little affinity for nicotinic receptors at the motor end plate [13,14]. This molecular inactivation by L-cysteine involves a nonenzymatic chemical reaction between the cysteine thiol group and the central 'olefinic' double bond in the fumarate forming a heterocyclic ring between the two quaternary heads (Fig.…”

“…Rapacuronium, developed by Organon, appeared to achieve this profile but was withdrawn from the market in 2001 due to inducing severe bronchospasm in some patients [29]. The bis-quaternary nondepolarizing neuromuscular blocker, GW280430A (also known as AV430A or gantacurium chloride), was originally developed by Glaxo Wellcome but was assigned to Avera Pharmaceuticals in 2002 [30,31]. This compound is degraded by chemical mechanisms in vivo and has been studied in human volunteers [32].…”
