Vascular endothelium plays a crucial role in vascular homeostasis and tissue fluid balance. To target endothelium for robust genome editing, we developed poly(ethylene glycol) Me ether-block-poly(lactide-co-glycolide) (PEG-b-PLGA) copolymer-based nanoparticle formulated with polyethyleneimine. A single i.v. administration of mixture of nanoparticles and plasmid DNA expressing Cas9 controlled by CDH5 promoter and guide RNA (U6 promoter) induced highly efficient genome editing in endothelial cells (ECs) of the vasculatures, including lung, heart, aorta, and peripheral vessels in adult mice. Western blotting and immunofluorescent staining demonstrated an ∼80% decrease of protein expression selectively in ECs, resulting in a phenotype similar to that of genetic knockout mice. Nanoparticle delivery of plasmid DNA could induce genome editing of two genes or genome editing and transgene expression in ECs simultaneously. Thus, nanoparticle delivery of plasmid DNA is a powerful tool to rapidly and efficiently alter expression of gene(s) in ECs for cardiovascular research and potential gene therapy. This study involved multiple reactions and reactants, such as 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0Safety of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one).
3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (cas: 38215-36-0) belongs to thiazole derivatives. The thiazole ring is notable as a component of the vitamin thiamine (B1). There are numerous natural products that possess a thiazole ring with broad pharmacological activities. Thiamine, also known as vitamin B1, possesses a thiazole ring linked with 2-methylpyrimidine-4-amine as hydrochloride salt.Safety of 3-(Benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one
