Potential Role of In Vitro-In Vivo Correlations (IVIVC) for the Development of Plant-Derived Anticancer Drugs

BACKGROUND

Conventional medicines, along with herbal formulations of Chinese, serve as the primary source and hub of active new drugs where the initial research concentrates on the extraction and isolation of bioactive lead compound(s) to treat several diseases largely for cancer. Plant-derived natural products and their analogs reveal a significant source of several clinically useful anticancer agents. Herbs and herbal derived active compounds play an unavoidable role in the treatment, drug discovery and delivery for decades, as evidenced by numerous existing marked drugs and various cancer-related molecular targets in clinical development.

OBJECTIVE

Solubility, resistance and metabolic limitations of the drug can be overcome by suitable molecular modifications. Due to enhancements in tumor targeting technology, some agents who failed in earlier clinical studies are also stimulating renewed interest. In this connection, In Vitro-In Vivo Correlation (IVIVC) plays an important role in the development of dosage forms in the field of pharmaceutical technology.

CONCLUSION

IVIVC tool fastens and improves the drug development process and product quality, which is also utilized in internal control for scale-up to improve formulations and alternative production processes. Most importantly, this IVIVC tool lessens the number of human studies during new pharmaceuticals developments. In this review, we would like to grab the attention of readers to the importance and significance of IVIVC for natural products of anticancer drugs examples such as Docetaxel, Etoposide phosphate, 6-Gingerol, Capsaicin, etc.

In Silico Assessment of ADME Properties: Advances in Caco-2 Cell Monolayer Permeability Modeling

One of the main goals of in silico Caco-2 cell permeability models is to identify those drug substances with high intestinal absorption in human (HIA). For more than a decade, several in silico Caco-2 models have been made, applying a wide range of modeling techniques; nevertheless, their capacity for intestinal absorption extrapolation is still doubtful. There are three main problems related to the modest capacity of obtained models, including the existence of inter- and/or intra-laboratory variability of recollected data, the influence of the metabolism mechanism, and the inconsistent in vitro-in vivo correlation (IVIVC) of Caco-2 cell permeability. This review paper intends to sum up the recent advances and limitations of current modeling approaches, and revealed some possible solutions to improve the applicability of in silico Caco-2 permeability models for absorption property profiling, taking into account the above-mentioned issues.
