Estratégia de simplificação molecular no planejamento racional de fármacos: a descoberta de novo agente cardioativo

Abstract: Recebido em 24/1/02; aceito em 17/4/02 STRATEGY OF MOLECULAR SIMPLIFICATION IN RATIONAL DRUG DESIGN: THE DISCOVERY OF A NEW CARDIOACTIVE AGENT. In this article are described examples of the successful use of molecular simplification strategy in the discovery of new drugs from bioactive natural products and synthetic compounds. The discovery of a new cardiotonic derivative (37, 2-thienylidene-3,4-methylenedioxybenzoylhydrazine; LASSBio-294), efficiently synthesized from Brazilian natural product and structurall… Show more

“…Recently, the lead compound 3,4-methylenedioxybenzoyl-2-thienylhydrazone (LASSBio-294) was synthesized from a Brazilian natural product obtained from sassafras oil, known as safrole. Synthesis was performed on the basis of molecular simplification of the pyridazinone phosphodiesterase inhibitors [6]. LASSBio-294 has been described as a potent cardiac inotropic agent [7] with vasodilator properties [8].…”

“…Desta forma, a comunidade médica e científica vem procurando compreender os fenômenos responsáveis pelos mecanismos adaptados de resistên-cia, de forma a criar alternativas e novas estratégias para o combate a bactérias resistentes. A demanda crescente por novas substân-cias 12 capazes de inibir, em concentrações baixas, processos vitais de uma ou mais espécies de microrganismos resistentes tem provocado uma verdadeira corrida em busca de agentes antibacterianos de origem natural, semissintética ou sintética cada vez mais eficientes. Apesar dos mais otimistas já terem abandonado o antigo sonho de encontrar uma substância antibacteriana "perfeita" (invencível frente a patógenos multirresistentes, com amplo espectro de ação e sem efeitos colaterais), o descobrimento de novos antibióticos potentes e mais seguros representa não apenas o avanço para uma melhor qualidade de vida, mas também a participação em um mercado em crescimento 13 que movimenta cerca de 25 bilhões de dólares.…”
