Neurotoxicity refers to direct or indirect effect of chemicals that disrupt the nervous system. Human beings are grieving from nervous related ailments due increase in the population and aging. Because of the limited capacity of neurons to regenerate there is still no trusted and consistent therapeutic approach available to treat neurodegenerative diseases. Natural compounds have been widely studied as potential neuroprotective agents because of their characteristics of multiple targets and low cytotoxicity. Endophytes could be any organism either bacteria fungi actinomycetes or mycoplasm which reside inside the tissues of plants showing mutualistic relationships without infecting any of the plant cells. Variety of novel secondary metabolites and known analogues of plant metabolites are produced by endophytic microbes. Structurally distinctive and therapeutically active natural products such as flavonoids phenolic acids polyketides terpenoids benzopyranones quinines steroids alkaloids etc. are obtained from endophytes for their potential use in medicine agriculture or industry. Considerable literature is also available on chemically diversified compounds isolated from endophytic fractions possessing neuroprotective activity. The present review emphasizes on promising neuroprotective metabolites isolated from endophytic microbes inhabited in medicinal plants.","PeriodicalId":21459,"journal":{"name":"RGUHS Journal of Pharmaceutical Sciences","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135910417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The codrugs approach was shown to be an effective strategy for targeting diseases synergistically hence improving the quality of life of patients. The present study aimed to synthesize various Nonsteroidal Anti-inflammatory Drugs NSAIDs and Calcium channel blocker CCB Co-drugs and biopharmaceutical study to eliminate the adverse gastrointestinal effects of the NSAIDs to treat comorbid conditions in geriatric patients with significant reduction of polypharmacy.Methods Various conjugates were synthesized by a one-pot amidation reaction of Amlodipine with various NSAIDs. Further characterization by melting point TLC Fourier transform infrared nuclear magnetic resonance and mass spectroscopy followed by solubility partition coefficient and hydrolysis study in SGF and SIF.Results The synthesized codrugs satisfied the structural criteria of the proposed plan. From the biopharmaceutical and hydrolysis study it was observed that the co-drugs underwent significant hydrolysis in SIF pH 7.4 and have showed delayed onset of action with respect to the standard drugs. The delayed onset may be due to the hydrolysis of amide linkage followed by the release of the prodrug which finally releases the active drug.Conclusion The findings illuminated the codrugs pros and cons aiding optimization and development. This research advances amide-based mutual prodrugs and their use in pharmaceutical research. The outcome of this exploration confirmed that the described co-drug can offer desirable safety and therapeutic benefits. Hence these conjugates could be considered for further development.","PeriodicalId":21459,"journal":{"name":"RGUHS Journal of Pharmaceutical Sciences","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135912888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
