Recent advances in dual-drug co-amorphous systems
Drug Discov Today. 2023 Dec 21:103863. doi: 10.1016/j.drudis.2023.103863. Online ahead of print.ABSTRACTPoor solubility of drugs and therapeutic candidates poses a significant challenge in drug research and development. Biopharmaceutical class II drugs exhibit limited absorption because of their weak solubility and high permeability. Co-amorphous systems (CAMs) have been studied widely as a way to improve the solubility of drugs. This review summarizes recent advancements in dual-drug CAMs, including improvements in formulation, manufacturing, and solid-state characterization, and highlights the importance of enhancing sol...

Human carnosinases: A brief history, medicinal relevance, and in silico analyses
Drug Discov Today. 2023 Dec 19:103860. doi: 10.1016/j.drudis.2023.103860. Online ahead of print.ABSTRACTCarnosine, an endogenous dipeptide, has been found to have a plethora of medicinal properties, such as antioxidant, antiageing, and chelating effects, but with one downside: a short half-life. Carnosinases and two hydrolytic enzymes, which remain enigmatic, are responsible for these properties. Hence, here we emphasize why research is valuable for better understanding crucial concepts like ageing, neurodegradation, and cancerogenesis, given that inhibition of carnosinases might significantly prolong carnosine bioavailabi...

Mechanisms and prospects of piezoelectric materials as smart delivery vehicles in cancer treatment
Drug Discov Today. 2023 Dec 18:103862. doi: 10.1016/j.drudis.2023.103862. Online ahead of print.ABSTRACTPiezoelectric materials, capable of converting mechanical energy into electrical energy and vice versa, have emerged as promising candidates for designing intelligent drug delivery vehicles. Leveraging their inherent electrical properties, these materials respond to external stimuli, such as mechanical forces and electrical signals, to control drug release. By integrating piezoelectric materials into drug delivery systems, we can achieve exacting control over drug-release mechanisms. Piezoelectric materials hold enormous...

GPR39: an orphan receptor begging for ligands
Drug Discov Today. 2023 Dec 18:103861. doi: 10.1016/j.drudis.2023.103861. Online ahead of print.ABSTRACTProgress in the understanding the receptor GPR39 is held up by inconsistent pharmacological data. First, the endogenous ligand(s) remain(s) contentious. Data pointing to zinc ions (Zn2+) and/or eicosanoids as endogenous ligands are a matter of debate. Second, there are uncertainties in the specificity of the widely used synthetic ligand (agonist) TC-G 1008. Third, activation of GPR39 has been often proposed as a novel treatment strategy, but new data also support that inhibition might be beneficial in certain disease con...
