A multicenter, randomized, open label, two formulation, crossover bioequivalence trial of doxorubicin hydrochloride liposomal injection in Chinese patients with metastatic breast cancer.

Purpose: The primary objectives of this trial were aimed at exploring the pharmacokinetic profiles and the human bioequivalence of an intravenous liposomal injection of doxorubicin hydrochloride in comparison with a reference formulation in Chinese patients diagnosed with metastatic breast cancer.

Methods: To achieve these goals, the trial employed a randomized, open-label, two-formulation crossover dosing strategy among Chinese patients with metastatic breast cancer. Pharmacokinetic (PK) evaluation was conducted through the collection of blood samples, and the liquid chromatography tandem mass spectrometry (LC/MS/MS) method was leveraged to quantify plasma concentrations of both liposome-encapsulated doxorubicin and non-encapsulated doxorubicin in patients.

Synthesis and structural modification of the natural product Ivesinol to discover novel autophagy activators.

Autophagy is a lysosome-dependent cellular degradation pathway that responds to a variety of environmental and cellular stresses, which is defective in aging and age-related diseases, therefore, targeting autophagy with small-molecule activators has potential therapeutic benefits. In this study, we successfully completed the first total synthesis of Ivesinol, an identified antibacterial natural product, and efficiently constructed a library of its analogs. To measure the effect of Ivesinol analogs on autophagic activity, we performed cell imaging-based screening approach, and observed that several Ivesinol analogs exhibited potent autophagy-regulating activity.

Pachymic acid activates TP53INP2/TRAF6/caspase-8 pathway to promote apoptosis in renal cell carcinoma cells.
