ABSTRACTHydroxychloroquine (HCQ) is a 4-aminoquinoline molecule used for the treatment of malaria, and more recently to treat rheumatoid arthritis, systemic lupus erythematosus, and cancer. In cancer, HCQ is being used in multiple cancer clinical trials as an inhibitor of autophagy, a cytosolic degradation process employing the lysosome. Importantly, more potent lysosomotropic agents are being developed as autophagy inhibitors. Additional studies revealed that acridine-based compounds such as quinacrine (QN) increased potency over the 4-aminoquinoline HCQ. In line with these initial discoveries, we performed chemical synthesis of acridine-based compounds and screened for potent autophagy inhibition. The novel compound VATG-027 increased potency and cytotoxicity over HCQ in osteosarcoma and melanoma cell lines, supporting further investigation in vivo. Here, we developed a liquid chromatography tandem mass spectrometry (LC-MS/MS) method to investigate HCQ, QN, and VATG-027 compound concentrations across various tissue types in mice. This method detected compound concentrations in whole blood, lung, liver, kidney, and subcutaneous tumor tissues. Concentrations of HCQ, QN, and VATG-027 varied within and between tissue types, suggesting unique tissue distribution profiles for 4-aminoquinoline and acridine compounds.

Bexarotene (BEX), a specific retinoic acid X receptor (RXR) agonist granted by Food and Drug Administration (FDA) approval for the clinical treatment of T cell lymphoma, has now been found to exert pharmacological effects in the nervous system, with low bioavailability and poor cerebral distribution limiting its application in treatment on neurological disorders. Pharmaceutical co-crystal was a helpful method to improve the bioavailability and tissue distribution of active pharmaceutical ingredients (APIs). Here, 2bexarotene-ligustrazine (2BEX-LIG), a novel co-crystal system of BEX and ligustrazine (LIG) of which with BEX is an API, was constructed with satisfactory stability and enhanced solubility. The pharmacokinetics characteristics of BEX were detected, and the results showed that the absolute bioavailability and the cerebral concentration of BEX in rats administrated with 2BEX-LIG were enhanced from 22.89% to 42.86% and increased by 3.4-fold, respectively, compared with those in rats administrated an equivalent of BEX. Hence, our present study indicated that the novel co-crystal of 2BEX-LIG contributed to improving BEX oral bioavailability and cerebral distribution, thereby providing significant advantages for clinical application of brain tumors and other neurological diseases.
