Abstract:
The manufacture of food products and dietary supplements using natural food colorants has been attracted attention in modern food industry. Carotenoids and anthocyanins as natural colorants show strong antioxidant and immunomodulation activities and may prevent degenerative diseases as well. The present research concerns the development of stepwise extraction procedures and HPLC analysis of carotenoids and anthocyanins containing agro-industrial waste materials (tangerine, orange peel and grape skin). Extractions were carried out in a dynamic supercritical fluid-carbon dioxide (SC-CO2) and ultrasound assisted extraction systems. The effects of operating pressure and temperature, extraction time, pH, flow rate of the SC-CO2, sample size and solvent nature used were investigated. The optimal conditions for extraction were found. The drying process of samples obtained from agro-industrial waste materials was studied as well. The main carotenoids-beta-carotene, lycopene and total anthocyanins obtained in organic extracts were quantified using new, rapid, effective and selective developed and validated HPLC methods. The HPLC methods were validated with respect to system suitability test, specificity, linearityrange, accuracy, precision, limit of detection (LOD) and quantitation (LOQ). The stability of solutions was studied as well. The calibration curves of developed HPLC methods are linear over a concentration range 0.08-6.50 μg/mL for beta-carotene (r2=0.9992), 0.34-200.20 μg/mL for lycopene (r2=0.9999); 0.04-80.50 μg/mL and 0.12-80.50 μg/mL for total anthocyanins expressed as cyanidine chloride (r2=0.9999) and kuromanine chloride (r2=0.9999); The average recovery equals to 106.8% for beta-carotene, 101.4% for lycopene, 95.62% for cyanidine chloride and 94.9% for kuromanine chloride.

Pharm Degree in Clinical Pharmacy and Pharmacology from the University of Dhaka in 2005 and 2006, respectively, she has been awarded the Ph.D Degree in Pharmacology by Hamdard University, NewDelhi, India in 2016.
Abstract:
The present study was intended to elucidate the effect of coumaroyl lupendioic acid, a new lupane-type triterpene isolated from Careya arborea (Lecythidaceae) stem bark, on the biomarkers of oxidative stress in Complete Freund's Adjuvant (CFA)- induced arthritic rats. Arthritis was induced by injecting 0.1 ml of CFA (5 mg/ml of heat killed Mycobacterium tuberculosis) into the sub plantar region of the left hind paw. Treatment with coumaroyl lupendioic acid (10 and 20 mg/kg, p.o.) and reference drugs (indomethacin and dexamethasone at the dose of 5 mg/kg, p.o.) were started on the day of induction and continued up to 28 days. The effect of coumaroyl lupendioic acid on oxidative indicators (e.g. nitric oxide, myeloperoxidase, malondialdehyde) and antioxidant enzymes (e.g. superoxide dismutase and glutathione peroxidase) was measured at the end of the study. Furthermore, ankle joints and spleen were collected and prepared for histological examination. The present study showed that the oxidative indicators such as nitric oxide, myeloperoxidase, malondialdehyde were downregulated by coumaroyl lupendioic acid. A significant upsurge in the level of superoxide dismutase and glutathione peroxidase was observed. Moreover, histopathological examination showed that the inflammatory cells infiltration, synovial hyperplasia and cartilage erosion had considerably improved on administration of coumaroyl lupendioic acid. In conclusion, our study strongly demonstrated that coumaroyl lupendioic acid has efficient scavenger and protective effect against oxidative stress elevated after CFA injection.

Title: Complement peptide C4a mitigates LPS-induced endothelium disruption, cytokine production, ERK activation, and [Ca2+] influx from human moncytes- A new therapeutic intervention for endotoxin shock
Time : 10:55:11:30
Biography:
Hongbin Wang received his PhD in 2010 from the University of Pennsylvania and Post-doctoral training from University of Pennsylvania Perelman School of Medicine. Now, he is an Assistant Professor of Pharmacology in the Department of Pharmaceutical and Biomedical Sciences at the California Nothstate University College of Pharmacy. He has published more than 40 papers in peer reviewed journals.
Abstract:
Activation of the complement cascade is a major effector of the inflammatory response. Cleavage of complement components in the course of activation produces low-molecular-weight peptides, including C3a, C4a, and C5a. Both C3a and C5a have potent anaphylatoxin properties. Our recent study idnetified that C4a mediates effector functions through binding to proteaseactivated receptors (PAR) 1 and PAR4. Early study demonstrated that animals with complement C4 deficiency were reported to be more susceptable to endotoxic shock, suggesting that C4 protects animals from endotoxic effects. However, the molecular mechanism for C4 protective effect on endotoxin shock in animals is poorly understood. We propose that C4 activation peptide, C4a, possiblly through binding to PAR1/4 on platelets, monocytes, and endothelial cells, inhibits LPS-induced platelet aggregation, IL-1β and TNFα cytokine production from monocytes, and endothelium permeability to achieve C4 protective effects in endotoxin shock animal models. In the present study, we found that pretreatment with C4a to human primary monocytes can significantly inhibit LPS-induced IL-1β and TNFα production. Moreover, LPS-induced ERK phosphorylation and [Ca2+] influx were significantly inhibited by the pretreatment of C4a. Our experiments also revealed that C4a significantly decreased endothelium permeability when human endothelial cells were cultured in the presence of LPS, indicating under endotoxemia condition, C4a prevents endothelium disruption. Our data provide deeper insight into the mechanism of C4’s protective effect on endotoxic shock and would provide a valuable resource for the wider scientific community to generate future therapeutic interventions for the treatment of clinical endotoxemia.

Abstract:
Statement of the Problem: Delivery via the lung represents a unique opportunity to circumvent the prostaglandin independent mucosal injury associated with the oral administration of NSAIDs, as it eliminates the direct GI exposures to these drugs. Furthermore, the pulmonary drug delivery route usually decreases the dose requirements by 10 to 20 folds. Additionally, a slower rate of respiratory decline is shown in cystic fibrosis patients on high, oral doses of IBU in comparison to placebo. Dry powder inhalation is the most versatile way of pulmonary administration of API. It allows numerous formulation variations and many different dry powder inhaler (DPI) devices to design a drug product matching therapeutic needs. The purpose of the present research was to formulate IBU dry powder inhalers (DPI) containing Carrageenan as a natural polymer and to indicate appropriate excipient and polymer to improve the aerodynamic properties of the DPI formulations.
Materials & Methods: Trehalose and leucine were dissolved in Carrageenan solution. IBU was added into the solution. The mixture was then sprays and dried with constant stirring using a Büchi Nanospray dryer B-90. The formulations were analyzed by thermogravimetry (Perkin Elmer 4000). The in vitro aerosolization performance was investigated using next generation impactor (Copley). In vitro dissolution studies were done with paddle over disc method USP apparatus 2.
Results & Discussion: Encapsulation efficiency and the Carr’s Index increased with increasing Carrageenan. The highest encapsulation efficiency value was 78.6±2.9. On the other hand, the process yield decreased with increasing carrageenan. The lowest process yield value was 71.16±1.7%. The fine particle fractions of the formulations were over 37.8±3.2% thanks to the nanospray dryer. The release of IBU was nearly complete within 8 hours with 1:1 drug: polymer.
Conclusions: In this study, IBU DPI containing carrageenan was obtaining with good process yield, aerolization properties and low cohesively.

Abstract:
Cleaning validation is a critical analytical responsibility of quality assurance system in pharmaceutical industry and ensures the efficiency of the cleaning routine procedure used in production which means that it is capable and effective in removing active pharmaceutical ingredient residues from the manufacturing equipment surfaces below a predetermined level and to prevent cross-contamination of next product. The aim of this study was to validate swab and rinse sampling procedures and demonstrate the applicability of developed HPLC method for quantitative estimation of alprazolam residues in cleaning control samples collected from pharmaceutical equpment surfaces after manufacturing of alprzolam 1 mg uncoated tablets.The swab and rinse sampling procedures were developed in order to obtain a suitable recovery (>90 %). The known amounts of alprazolam are spiked onto representative surfaces, which are dried, sampled and analyzed using the validated HPLC method. Additionally, the robustness of sampling procedures was assessed. For swab sampling the surface (sampling area - 5 × 5 cm2) was successively wiped with one micro polyester swab (3×2.5×10 mm) moistened with diluent – methanol. The method was developed using LC system “Ag 1260 Infinity” and Prodigy C8(2) 250 × 4.0 mm, 5 μm column with a mobile phase - a mixture of methanol, phosphate buffer pH 3.0 and acetonitrile (10 : 45 : 45 v/v); The flow rate – 1.4 ml/min; The detector wavelength - 220 nm; The injection volume – 20 μL; The column temperature – 300C. The method was validated with respect to robustness, system suitability test, specificity, linearity-range, accuracy, precision (intra-day and inter day), limit of detection (LOD) and quantitation (LOQ). The stability of alprazolam solutions was also studied. These studies were performed in accordance with established ICH Q2 guideline. The calibration curve is linear r2=1.00000 over a concentration range 0.025 – 10 μg/mL; LOD - 0.005 μg/mL and LOQ - 0.025 μg/mL.

Title: Enhancement of solubility and bioavailability of Clopidogrel by selfnanoemulsifying drug delivery system
Time : 13:50-14:25
Biography:
Abstract:
A self-nanoemulsifying drug-delivery system (SNEDDS) has been explored to improve the solubility and dissolution profile of poorly soluble drug clopidogrel. Different formulations were prepared using different oils, surfactants and cosurfactants. A pseudo ternary phase diagram was constructed to identify the self-micro emulsification region. Further, the resultant formulations were investigated for clarity, phase separation, drug content, % transmittance, globule size, freeze-thaw, in vitro dissolution studies, particle size analysis and zeta potential. On the basis of particle size, zeta potential and dissolution profile and other studies, F6 was found to be the best formulation of clopidogrel SNEDDS. The particle size of the emulsion is a crucial factor in self-emulsification performance because it determines the rate and extent of drug release as well as absorption. The average particle size of clopidogrel SNEDDS for transparent micro-emulsions should be less than 50nm. The particle size of the optimized SNEDDS formulation was found to be 5.2 nm and zeta potential was found to be -29 mV which comply with the requirement of the zeta potential for stability. The faster dissolution from SNEDDS may be attributed to the fact that in this formulation, the drug is a solubilized form and upon exposure to dissolution medium results in small droplet that can dissolve rapidly. The % release from optimized SNEDDS formulation F6 was highest (98.93%) and faster than other SNEDDS formulations and pure drug substance indicating influence of droplet size on the rate of drug dissolution. FTIR data revealed no physicochemical interaction between drug and excipients. Thus clopidogrel with SNEDDS formulation may be used for the improvement of solubility and dissolution rate in the effective management of heart disease.
