COVID-19 Associated Mucormycosis::A Review of an Emergent Epidemic Fungal Infection in 3 Era of COVID-19 Pandemic
At a time when the COVID-19's second wave is still picking up in countries like India, a number of reports describe the potential association with a rise in the number of cases of mucormycosis, commonly known as the black fungus. This fungal infection has been around for centuries and affects those people whose immunity has been compromised due to severe health conditions. In this article, we provide a detailed overview of mucormycosis and discuss how COVID-19 could have caused a sudden spike in an otherwise rare disease in countries like India. The article discusses the various symptoms of the disease, class of people most vulnerable to this infection, preventive measures to avoid the disease, and various treatments that exist in clinical practice and research to manage the disease
DESIGN AND ANTICANCER ACTIVITY PREDICTION OF DIHYROPYRIMIDINONE BASED NOVEL INHIBITORS OF P53-MDM2 INTERACTION
  Objective: P53 protein is well known for its role in cell cycle regulation and induction of apoptosis. This protein is degraded by MDM2 mediated proteolysis. Inhibition of interaction between p53 and MDM2 has been recognized as a most potential and selective target for development of novel anticancer agents. Recently, several molecules entered in the clinical trial study for the treatment of various types of cancers are based on inhibition of interaction between p53-MDM2. Therefore, in this study, a novel dihydropyridine based molecules were designed as p53-MDM2 inhibitor, and their anticancer activity (including reference) was determined in comparison with most active anticancer agent and inactive anticancer agents in National Cancer Institute database using Cancer IN†server.Methods: In this work, a novel dihydropyrimidinone based lead (L11) on the basis of molecular docking study, predicted IC50, anticancer activity, and toxicity profile were designed. Lead L11 was obtained after sequential isosteric replacement of functional groups for optimization in compound L0.Results: The docking scores of L3-L11 found to be in range of 21-25 close to docking score 25 of SAR405838 and better than nutlin-3a. MDM2 binding affinity values (37-78 Kcal/mol) of all ligands were also found to better than that of nutlin-3a (37 Kcal/mol). Surprisingly, MDM2 binding affinity of L11 (78 Kcal/mol) found to be equal to that of SAR405838 and 2-fold greater than nutlin-3a.Conclusion: These data indicating that L11 as a potential lead from dihydropyrimidinones for inhibition of p53-MDM2 interaction
FORMULATION OF CURCUMIN NANOSUSPENSION USING BOX-BEHNKEN DESIGN AND STUDY OF IMPACT OF DRYING TECHNIQUES ON ITS POWDER CHARACTERISTICS
  Objective: The objective of this study was to formulate curcumin nanosuspension (NS) using Box-Behnken design (BBD) and solvent-antisolvent technique to overcome the challenges related to its poor dissolution rate.Methods: Sodium lauryl sulfate (SLS) and poly vinyl pyrrolidone K-60 (PVPK-60) have been used as a surfactant and polymer, respectively, to stabilize the NS. Ethanol was used as solvent to dissolve curcumin and water was used as antisolvent. The study revealed that SLS to curcumin ratio, PVPK-60 to curcumin ratio, solvent to antisolvent ratio and speed of mixing were the critical parameters that affected particle size and zeta potential of the formulation. Hence, based on Box- BBD, 25 formulations were prepared by varying these critical parameters. The optimized batch of CRM NS was further solidified using spray drying as well as rotary evaporation techniques to have a better insight for selection of solidification process in terms of retention of particle size, charge, flow, dissolution, and stability.Results: About 39.47 folds decrease in particle size of raw CRM was observed after conversion into NS. Further, about 53.57 and 45.45 folds decrease in particle size was observed after spray drying and rotary evaporation. Both the dried nanoparticles have shown comparatively higher solubility, powder flow, and dissolution rate as that of raw CRM. Powder X-ray diffraction study revealed the formation of amorphous nanoparticles. Accelerated stability study revealed that nanoparticles dried by spray drying were able to retain the properties such as particle size, flow, and dissolution rate as compared to rotary evaporated powders.Conclusion: It can be concluded that spray drying technique could offer many advantages while loading CRM nanoparticles into tablets for their oral administration
