k-Estrofantosídeo

Descrição:

k-Estrofantosídeo, com o número CAS 33279-57-1, é um glicosídeo cardíaco derivado das sementes do gênero Strophanthus, particularmente de Strophanthus gratus. É caracterizado pela sua capacidade de inibir a enzima Na+/K+ ATPase, o que leva ao aumento das concentrações intracelulares de sódio e cálcio, melhorando, em última análise, a contratilidade cardíaca. Este composto exibe uma estrutura que inclui um núcleo esteroide com um grupo de açúcar, contribuindo para sua atividade biológica. k-Estrofantosídeo é conhecido por suas potenciais aplicações terapêuticas no tratamento de condições cardíacas, particularmente insuficiência cardíaca e arritmias, devido aos seus efeitos inotrópicos positivos. No entanto, também possui uma janela terapêutica estreita, exigindo monitoramento cuidadoso da dosagem para evitar toxicidade. A substância é tipicamente administrada em um ambiente médico controlado, e sua farmacocinética pode ser influenciada por vários fatores, incluindo variáveis específicas do paciente e medicamentos concomitantes. Assim como outros glicosídeos cardíacos, é essencial considerar os potenciais efeitos colaterais, como distúrbios gastrointestinais e arritmias, ao avaliar seu uso na prática clínica.

K-Strophanthoside

CAS: 33279-57-1

K-Strophanthoside is a cardiac glycoside, which is a bioactive compound derived from the seeds of certain Strophanthus species, a genus of plants native to Africa. This compound exhibits its mode of action by inhibiting the sodium-potassium ATPase enzyme on cell membranes, leading to an increase in intracellular sodium levels. Consequently, the sodium-calcium exchanger is affected, resulting in elevated intracellular calcium concentrations. This cascade enhances cardiac contractility, which can be beneficial in treating certain types of heart failure.
