“…The pharmacological activities of Tabebuia species are often related to the presence of saponins, fl avonoids, coumarins and natural antibiotics (Miranda et al, 2001;Machado et al, 2003;Falcão et al, 2005), while the chemical profi le presented by most to these studies have shown the quinones as the main active substances (Santana et al, 1968;Ueda et al, 1994;Pinto et al, 2000;Miranda et al, 2001;Machado et al, 2003).…”

“…Essa naftoquinona já foi produzida e comercializada como medicamento para o tratamento de alguns tipos de câncer, mas não esta mais disponível no mercado em decorrência dos efeitos colaterais que acabavam agravando o estado clínico dos pacientes em tratamento, entre eles, a anemia, distúrbios de coagulação sanguínea e gastrointestinais (Da Silva et al, 2003;Oliveira et al, 1990). Além da atividade citotóxica, outras atividades biológicas já foram atribuídas ao lapachol, tais como antiparasitária ( Goulart et al, 1997;Pinto et a., 2000), antimicrobiana, antifúngica (Garnier et al, 1996), anti-inflamatória (Almeida, 1990), entre outras.…”
