Podophyllin, an ethanolic extract of Podophyllum peltatum L. or P. emodi Wall (syn. P. hexandnum Royle), is a good source of the aryltetralin-type lignan, podophyllotoxin. The latter compound, as well as its congeners and derivatives exhibit pronounced biological activity mainly as strong antiviral agents and as antineoplastic drugs. The podophyllotoxin derivatives etoposide, etopophos (etoposide phosphate), and teniposide are thus successfully utilized in the treatment of a variety of malignant conditions. Continued research on the Podophyllum lignans is currently focused on structure optimization to generate derivatives with superior pharmacological profiles and broader therapeutic scope, and the development of alternative and renewable sources of podophyllotoxin.

Purpose: Gastrointestinal (GI) injuries post ionizing radiation (IR) becomes a crucial factor in survival. Thus, the current study was aimed to explore the molecular mechanisms behind IR produced GI proteome alterations and their amelioration by a safe radioprotective formulation candidate, G-003M (podophyllotoxin+rutin).Materials and method: C57BL/6 mice were administered with G-003M 1 h before 9 Gy whole body γ irradiation. 2DE-MS analysis was conducted to identify differential expression of jejunum proteins with fold change >1.5 (p < .05) at various time-points. Results: G-003M pre-administration decreased total number of differential proteins. It mediated protection to cytoskeleton, modulated stress, apoptosis and inflammatory proteins. Direct effect on eukaryotic translation initiation factor 4H (Eif4h), thioredoxin domain-containing protein 17 (Txndc17) and interferon-induced protein 35 (Ifi35) was observed. Bioinformatics depicted transcription factor-MYC, was also positively modulated by G-003M. Further, it also enhanced level of citrulline (ELISA analysis), and restored crypts and villi lengths (histological analysis) against severe damage caused by lethal irradiation.Conclusion: Current findings reveal that G-003M may be an efficient candidate in protecting key proteins of metabolic and biochemical pathways assisting in the rapid recovery of GI proteome. This fairly improved the chances of animal survival exposed to lethal doses of whole body radiation.

Podophyllotoxin (PPT) is a lignan extracted from podophyllum genera and it shows potent antitumor activity since it could effectively inhibit the assembly of microtubule in tumor cells. However, the effects of podophyllotoxin exposure on porcine oocyte quality is still unclear. In present study we tried to examine whether podophyllotoxin exposure was toxic to porcine oocyte maturation. Our results showed that podophyllotoxin exposure inhibited porcine oocyte maturation, showing with the failure of polar body extrusion, and the inhibitory effects of podophyllotoxin on porcine oocytes was dose-depended. Moreover, the meiotic spindle formation was disturbed and the chromosomes were misaligned in the podophyllotoxin-treated porcine oocytes. However, there was no different expression for p-MAPK and ace-tubulin between the control and podophyllotoxin treatment group. In addition, after 0.01 μM podophyllotoxin treatment, the intracellular reactive oxygen species (ROS) levels and the Annexin-V signal at MI stage significantly increased compared to the control group, indicating the occurrence of oxidative stress and early apoptosis. Taken together, our results suggested that the toxic effects of podophyllotoxin exposure on porcine oocyte maturation might be through its effects on spindle formation and the induction of oxidative stress-mediated early apoptosis.
