L-Threonolactone | MedChemExpress (MCE) 1 mg  | ≥98.00%

MedChem Express

L-Threonolactone ((3R,4S)-3,4-Dihydroxyoxolan-2-one) is a purine nucleoside analog. Purine nucleoside analogs have broad antitumor activity targeting indolent lymphoid malignancies. Anticancer mechanisms in this process rely on inhibition of DNA synthesis, induction of apoptosis, etc[1].

L17E | MedChemExpress (MCE) 1 mg  | ≥98.00%

MedChem Express

L17E, an endosomolytic peptide, is a cationic amphiphilic peptide with specific membrane lytic activity for late endosomes (LEs). L17E diminishes the TS5-p45 induced apoptosis in a dose-dependent manner. L17E is endocytosed into cells and trafficked to LEs. Within the acidic environment of LEs, L17E perturbs and lyses the LE membrane, leading to disruption of LE […]
