Abstract:

The full potentials of the herbal products are mainly not utilized due to the insufficient knowledge of the holistic quality & chemical composition of most herbal products. The growth potentials of the herbal product industry can only be achieved if the composition of herbal product is standardized in order to ensure proper quality control and accountability. In recent years more people throughout world have realized to use herbal products in health care system. Worldwide need of alternative medicine has resulted in growth of herbal product markets and interest in traditional systems of medicine. Herbal drug technology is used for converting botanical materials into medicines, where standardization and quality control with proper integration of modern scientific techniques and traditional knowledge is important. In order to prove constant composition of herbal preparations, adequate analytical methods such as photometric analysis, thin layer chromatography, high performance liquid chromatography, gas chromatography, DNA fingerprinting and metabolomics are used. Phytochemical standardization encompasses all possible information generated with regard to the chemical constituents present in herbal products. In recent years World Health Organization and many herbal industries worldwide have emphasized on the importance of qualitative and quantitative methods for characterizing the samples, quantification of the biomarkers, chemical markers and the fingerprint profiles. If principle active components are known, it is most logical to quantify these compounds. My talk will cover current trends, challenges and advances in quality control and standardization of herbal products.

Abstract:

Results:  A.  biochemical  analysis:  ATT  treated  rats  showed  significant  increase  in  AST (aspartate    aminotransferases),    ALT    (alkaline    liver    transferase),    ALP    (alkaline    liver phosphatases), and GGT (γ-glutamyl transferase) in the serum Vs. control (P<0.05).  Treatment of silymarin and Cl (100 and 200 mg/kg)  extract showed hepatoprotective activity against the hepatic  damage  induced  by  ATT.  This  was  evident  from  significant  reduction  in  serum  liver enzymes levels ALT, AST, ALP, GGT and also there was significant increase in serum albumin and  total  proteins  as  compared  to  the  ATT  treated  groups  (P<0.05).  B.  Histopathology:  ATT treated  rats  histopathological  slides  revealed  mild-moderate  fibrosis,  low  grade  inflammation, hepatocellular  necrosis  with  sinusoidal  dilatations  suggestive  of  congestion  and  significant hepato-protective changes were found when Cl extract was treated with ATT drugs.

Conclusions: The hepato-protective action combined with antioxidant activity has a synergistic effect  to  prevent  the  process  of  initiation  and  progress  of  hepatocellular  damage.  Thence,  we conclude  that  aqueous  extract  of  Cl is  a  promising hepato-protective  agent  could  be  clinically useful when added with ATT drugs.

Abstract:

The process of developing a new drug for use in medical practice takes an average of 10 to 15 years at a staggering cost ranging from 800million to 1 billion USD.  This leaves an impression that drug development can only be done by rich countries while the poor ones have no hope at all. The richness and diversity of flora and fauna all over the world speak about equitability and balance in opportunities. Developed countries are now reaching out to less developed ones offering trainings and skill transfer to help build the research capability of the latter. In return, developing countries offer their raw data and potential leads for further studies with fair sharing in intellectual properties towards novel drug development. Opportunities are available and these will be discussed in my talk.  Additionally, some research processes can be streamlined according to the research capacity and capability of each institution in order to come up with innovative but useful products that can be readily utilized by the community with minimal cost of production.

Abstract

Quality by Design (QbD) concept is a systematic approach towards development of product that begins with predefined objectives and emphasizes product and process understanding and process control, based on sound science and quality risk management. Recent pharmaceutical regulatory documents have stressed the critical importance of applying QbD principles for in-depth process understanding to ensure that product quality is built in from the onset of manufacturing process. The use of Herbal medicines is on rise all over the world due to their promising therapeutic effects and fewer adverse effects. This has led to phenomenal increase in the demand for herbal medicines in the last two decades. The manufacturing process for the herbal drug products is complex and involves many unit operations. It is therefore significant to develop manufacturing process under the framework of QbD, which aims to build the quality of herbal drug product from the onset of its manufacturing process.

The concept has been widely accepted and applied in the pharmaceutical manufacturing industry. There are still issues that need to be addressed in the implementation of QbD for Herbal drugs. Some of these issues discussed in the lecture are, variation in the quality of herbal raw material and identification of the correct source and such as extraction and suitable formulation, defining the critical quality attributes during development of herbal drug product. Therefore this presentation aims to give an brief information regarding the application of QbD principle to improve the process development and formulation of herbal drug product.

Abstract:

A review of the regulatory status of herbal drugs/products was done for few countries. A critical assessment was done, to know the hindrances in the process of harmonization of herbal products. It has been found that there is a lack of harmonization in the regulatory requirements of herbal products internationally, besides the issues of availability of herbs and their conservation. Quality by design is a crucial part of the modern approach to pharmaceutical quality. “Quality could be planned and most of quality deficit arises in the way process is planned and developed”, this thought of well-known quality expert Joseph Moses Juran gives foundation to the concept of quality by design (QbD). It refers to a new approach to product development that could increase efficiencies, provide regulatory relief and flexibility. Recently, the US Food and Drug Administration introduced quality by design (QbD) as a fundamental pharmaceutical quality model to be considered in the process and product development of pharmaceuticals. QbD concept has been supported by International Conference on Harmonisation (ICH) guidelines Q8 (R2). The beneficial impact of herbs on human health have been used for centuries and widely accepted by patients to the present day. The efficacy of herbal drugs often results from a complex composition of substances. The complexity of herbal drugs is the major reason for the lack of satisfactory studies into their effect and causes problems for the definition and assurance of quality. The implementation of QbD enables robust manufacturing process, and facilitate product quality. Herbs have in general a broad variety of compounds depending on growth and harvesting conditions. A suitable process design rated by the QbD principals can ensures a robust process from extraction to purification of herbal drugs in spite of their complex nature. Quality by Design is a powerful development approach that offers a number of technical, quality, and regulatory dividends. Hence application of quality by design (QbD) for development of herbal drugs can give rise to improved understanding of process which in turn will facilitate proper identification of sources of variation, management of variability by process design, and prediction of product quality attributes.

Abstract:

agents from natural products continues to be an important field in the face of multi-drug resistance and re-emerging infections. Many studies in the Philippines have reported plant products that have antimicrobial potential. However, a huge gap in the natural products-based antimicrobial research in the Philippines remains in terms of studying antimicrobial mechanisms of action. This scoping study aimed to document the antimicrobial assessment methodologies employed by natural products researchers in the Philippines. Methodology and Theoretical Orientation: Published scientific articles were searched in databases like Google Scholar and HERDIN using the keywords antimicrobial+plants+ Philippines, antibacterial+plants+Philippines, antifungal+plants+ Philippines. Outputs of research laboratories in HEIs in Mindanao that perform natural products research were also given special attention. Findings: Initial results show that Disk Diffusion Assays are routinely used to screen for antimicrobials from crude extracts. Very few papers report using Disk Diffusion Assay guided by TLC bioautography. MIC determination by broth macrodilution is common. MIC-MBC determination was also reported. No studies on mechanisms of action (e.g. using flow cytofluorometry, effects on MDT) were found. Conclusion and Significance: The nature of published antimicrobials research from natural products in the Philippines is limited to early-stage establishment of antimicrobial potential. Studies that elucidate the mechanisms of action of these antimicrobials must be undertaken, with appropriate infrastructure and funding support, to complete the development of antimicrobial products.

Abstract:

Statement of the Problem: Melanoma is the most fatal and life threatening type of skin cancer with increasingly higher rates of occurrence worldwide.  Although it accounts for 1% of all skin cancers, most of the skin cancer related deaths (75%) occur due to melanoma. Despite extensive clinical research, only few drugs have been approved by United States Food and Drug Administration (USFDA) for melanoma therapy. Most of these drugs kill normal healthy cells besides cancer cells. At present, the overall success rate of current modalities for this chemoresistant and metastatic melanoma is rather restricted. Hence there is an intense need for natural compounds, which can precisely treat melanoma with little or no toxicity on normal cells and prevent its progression to metastatic stage. The objective of the present study is to develop, optimize and evaluate curcumin loaded nanovesicular formulations for the treatment of melanoma. Methodology: The curcumin loaded nanovesicles (ethosomes and transfersomes) were prepared by cold and thin film hydration method respectively. The prepared nanovesicles were evaluated for size, zeta potential, entrapment efficiency, in vitro skin permeation and deposition studies. The optimized formulations were evaluated for in vitro cytotoxicity and cellular uptake studies using A375 human melanoma cells. Findings: The optimized nanovesicular formulations were found to be spherical and unilamellar structures having nanometric size range and high entrapment efficiency. The curcumin loaded nanovesicles showed significant skin permeation and deposition in the skin layers. The fluorescence microscopy study confirmed the enhanced penetration of nanovesicles into the deeper skin layers.  The in vitro cytotoxicity and cellular uptake studies revealed that curcumin ethosomes had significantly improved cytotoxicity and cellular uptake in A375 human melanoma cell lines. Conclusion & Significance: The present study provides a strong rationale for further investigation of newly developed curcumin nanovesicular formulations as a potential therapeutic strategy for melanoma treatment
