In vivo evaluation of enhanced drug carrier efficiency and cardiac anti-hypertrophy therapeutic potential of nano-curcumin encapsulated photo-plasmonic nanoparticles combined polymerized nano-vesicles: A novel strategy

摘要

Curcumin, a naturally derived polyphenolic compound has potent activities against cardiac disease like reducing hypertrophy, increasing antioxidant activity, maintaining hormone levels and blood pressure etc. Polymeric curcumin nanoparticles is a solemn concern nowadays in accordance to improve the beneficial properties of curcumin by diminishing its disadvantages like hydrophobic nature thereby results in maximum delivery of drug curcumin at the target. This study demonstrated the application of curcumin capped gold loaded poly (lactic-co-glycolic acid) nanoparticles (CAu-PLGA Nps) for the inhibition of cardiac hypertrophy by preserving myocardial functions of Wister rat model. Rat models were arbitrarily divided into five groups and observation period was 10 weeks; 1. Control 2. Enalopril (EP), an hypertropic agent induced group 3. EP and Curcumin (C) 4. EP and Curcumin capped gold (CAu) Nps and 5. EP and CAu-PLGA Nps injected group. CAu-PLGA Nps was first synthesized from double emulsion -solvent evaporation method and were characterized by its adoptable techniques such as FT-IR, XRD, SEM and TEM analysis. These analyses demonstrate the encapsulation of curcumin capped gold nanoparticles into PLGA there confirms the successful synthesis of CAu-PLGA Nps. Animals studies illustrates that the CAu-PLGA Nps has significantly produced cardiac anti-hypertrophy and drug delivery when compared to the other groups. CAu-PLGA Nps exhibit increased survival rate, improved cardiac functions like cardiac systolic and diastolic function, maintaining heart weight and left ventricle pressure at the controlled level. Beneficiary activities of CAu-PLGA Nps were associated with its cardiovascular functions like anti-inflammatory, antioxidant, controls cardiomycete growth, increased drug delivery, prevents accumulation of cholesterol and prevents myocardial infarction.
