Research Progress of Indole Alkaloids: Targeting MAP Kinase Signaling Pathways in Cancer Treatment

Cancer is the leading cause of morbidity and mortality in people throughout the world. There are many signaling pathways associated with cancerous diseases, from which the Mitogen-activated protein kinase (MAPK) pathway performs a significant role in this regard. Apoptosis and proliferation are correlated with MAPK signaling pathways. Plenty of experimental investigations were carried out to assess the role of indole alkaloids in MAPK-mediated cancerous diseases. Previous reports established that indole alkaloids, such as vincristine and evodiamine are useful small molecules in cancer treatment via the MAPK signaling system. Indole alkaloids have the anticancer potential through different pathways. Vincristine and evodiamine are naturally occurring indole alkaloids that have strong anticancer properties. Additionally, much research is ongoing or completed with molecules belonging to this group. The current review aims to evaluate how indole alkaloids affect the MAPK signaling pathway in cancer treatment. Additionally, we focused on the advancement in the role of indole alkaloids, with the intention of modifying the MAPK signaling pathways to investigate potential new anticancer small molecules. Furthermore, clinical trials with indole alkaloids in cancer treatment are also highlighted.

Formulation and Evaluation of Superporus Hydrogel Composite as a Gastro Retentive Drug Delivery for Cefditoren Pivoxil

The purpose of this work was to incorporate superporus hydrogels for cefditoren pivoxil by using polymer like poly acrylic acid aqua cc polymer and composite agent like cross linked sodium carboxy methyl cellulose in the presence of N,N-methylene-bis-Acrylamide as crosslinking agent. Pluronic F-127 as a stabilizer and ammonium per sulfate and tetramethylene diamine as a initiator pair. Poly acrylic acid aqua cc polymer-cross linked sodium carboxy methyl cellulose superporus hydrogels of cefditoren pivoxil were incorporate by gas blowing technique. The reaction  of pH on the swelling ratio was decisive. Swelling reversibility research was also achieve. Fourier transform infrared spectroscopy analysis and scanning electron microscopy studies were assume to indicate the drug loaded superporous hydrogels, while dissolution studies were achieve to assess release characteristics. Swelling was hugely depending on the term of crosslinking and the quantity of the polymer existing in formulation. The huge amount of cross-linking agent reduced the swelling ratio. The superporous hydrogels were hugely perceptive to pH of swelling medium, and exhibit reversible swelling and de-swelling behavior during still keep their mechanical stability. Apparent density was reliant on the amount of the superporous hydrogels and reduced with developing crosslink density. Degradation kinetics reveals that poly acrylic acid aqua cc polymer superporous hydrogels had good water holding potential. Drug release was similar to quantity of cross-linking agent. The studies report that poly acrylic acid aqua cc polymer superporous hydrogels can be used as a Gastroretentive drug delivery system in view of their swelling characteristics in acidic pH.
