Research Projects

Pyrano[2,3-c]pyrazole and its derivatives have gained significant attention due to their diverse and potent biological activities. Numerous studies have focused on developing biologically active pyranopyrazole derivatives, including 1,4-dihydropyrano[2,3-c]pyrazole (1,4-DHPP), 2,4-dihydropyrano[2,3-c]pyrazole (2,4-DHPP), 4-hydropyrano[2,3-c]pyrazole (4-HPP), and SHPP derivatives, particularly in medicinal chemistry. These compounds exhibit a wide range of biological properties such as anticancer, anti-tumor, anti-inflammatory, antibacterial, antimicrobial, and cardiovascular activities, among others. Efforts are ongoing to improve their bioavailability, especially through the development of water-soluble derivatives. Recently, a few chiral pure pyranopyrazole derivatives have demonstrated promising biochemical activities. Future research is expected to explore additional chiral derivatives, with a particular focus on chirality at the 4-position of 1,4-DHPPs, 2,4-DHPPs, and 4-HPPs. These chiral centers are anticipated to enhance biochemical potential by facilitating stronger and more selective binding to receptor or enzyme sites. Such advancements could drive innovation in both academic and pharmaceutical research, leading to the discovery of new biologically active pyranopyrazole derivatives. Pyranopyrazoles, a class of fused five- and six-membered heterocyclic compounds containing nitrogen and oxygen, have also demonstrated a range of pharmacological activities, including analgesic, vasodilatory, anticonvulsant, and molluscicidal properties. Recent studies highlight their potential as human Chk1 kinase inhibitors, further emphasizing their importance in medicinal chemistry. Our current project aims to synthesize potent anticancer agents and their derivatives (e.g., compounds 33–43) using green chemistry approaches. This includes employing microwave-assisted and electrocatalytic synthesis methods starting from simple, cost-effective materials to minimize environmental pollution. By prioritizing sustainability, we aim to produce new pyrano[2,3-c]pyrazole derivatives, which will subsequently be evaluated for their biological activities. These efforts represent a significant step toward the design and application of innovative DHPP derivatives in medicinal and pharmaceutical chemistry. These types of heterocyclic compounds hold significant potential beyond medicinal applications, particularly as light-absorbing ligands in combination with TiO₂ and CuO. This unique property makes them promising candidates for use in water-splitting processes to generate hydrogen, a clean and sustainable energy source.
