Azophotoswitches containing thiazole, isothiazole, thiadiazole, and isothiadiazole.

We report a novel class of azophotoswitches incorporating various five-membered heteroaryl units such as thiazole, isothiazole, thiadiazole, and isothiadiazole. These azophotoswitches were developed through an initial screening of 24 compounds using DFT calculations to identify those with the wavelength of maximum absorption () at a long wavelength. Subsequently, eight selected azophotoswitches were synthesized.

Drug Delivery Systems for Natural Medicines in Cancer Therapy.

Cancer stands as a prominent global cause of mortality, with chemotherapy using synthetic drugs being the predominant treatment method. Despite its high success rate, this approach is constrained by substantial side effects. Herbal medicines, known for their diverse bioactive components, exhibit promising anticancer attributes.

Three-Dimensionally Printed Agarose Micromold Supports Scaffold-Free Mouse Ex Vivo Follicle Growth, Ovulation, and Luteinization.

Ex vivo follicle growth is an essential tool, enabling interrogation of folliculogenesis, ovulation, and luteinization. Though significant advancements have been made, existing follicle culture strategies can be technically challenging and laborious. In this study, we advanced the field through development of a custom agarose micromold, which enables scaffold-free follicle culture.

Oocyte-specific EXOC5 expression is required for mouse oogenesis and folliculogenesis.

EXOC5 is a crucial component of a large multi-subunit tethering complex, the exocyst complex, that is required for fusion of secretory vesicles with the plasma membrane. Exoc5 deleted mice die as early embryos. Therefore, to determine the role of EXOC5 in follicular and oocyte development, it was necessary to produce a conditional knockout (cKO), Zp3-Exoc5-cKO, in which Exoc5 was deleted only in oocytes.

Caging Bioactive Triarylimidazoles: An Approach to Create Visible Light-Activatable Drugs.

Imidazoles are crucial structural components in a variety of small-molecule inhibitors designed to target different kinases in anticancer treatment. However, the effectiveness of such inhibitors is often hampered by nonspecific effects and the development of resistance. Photopharmacology provides a compelling solution by enabling external control over drug activity with spatiotemporal precision.
