AB  - Seven previously undescribed jatrophane diterpenoids, nicaeenin A-G, with eight known jatrophane diterpenoids, namely euphodendrophanes A-C, F, N, O, Q S, were isolated from latex of Euphorbia nicaeensis collected in Serbia. The chemical structures of the compounds were determined by spectro-scopic analysis including 1D and 2D NMR and HRESIMS experiments. All but one of the previously undescribed jatrophanes, showed significant potential to inhibit P-glycoprotein (P-gp) activity in two MDR cancer cells (NCI-H460/12 and DLD1-TxR). The most powerful were nicaeenin F and nicaeenin G. Moreover nicaeenin G significantly stronger sensitized NCI-H460/R cells to DOX than Dex-VER.

AB  - Medicinal plants are recognized from ancient times as a source of diverse therapeutic agents and many of them are used as dietary supplements. Comprehensive approaches are needed that would identify bioactive components with evident activity against specific indications and provide a better link between science (ethno-botany, chemistry, biology and pharmacology) and market Recently, the bark of black alder (Alnus glutinosa) appeared at market in the form of food supplement for treatment of different skin conditions. This study aimed to evaluate protective effects of two diarylheptanoids isolated from the bark of black alder: platyphylloside, 5(S)-1,7-di(4-hydroxyphenyl)-3-heptanone-5-O-beta-D-glucopyranoside (1) and its newly discovered analog 5(S)-1,7-di(4-hydroxyphenyl)-5-O-beta-D-[6-(E-p-coumaroylglucopyranosyl)]heptane-3-one (2) towards doxorubicin damaging activity. To that end, we employed HaCaT cells, non-cancerous human keratinocytes commonly used for skin regenerative studies. Diarylheptanoids significantly antagonized the effects of doxorubicin by lowering the sensitivity of HaCaT cells to this drug. Compound 2 prevented doxorubicin-induced cell death by activating autophagy. Both land 2 protected HaCaT cells against doxorubicin-induced DNA damage. They significantly promoted migration and affected F-actin distribution. These results indicate that chemo-protective effects of diarylheptanoids may occur at multiple subcellular levels. Therefore, diarylheptanoids 1 and 2 could be considered as protective agents for non-cancerous dividing cells during chemotherapy.

AB  - Multi-drug resistance (MDR) is a major obstacle to successful cancer treatment. Therefore, in vitro models are necessary for the investigation of the phenotypic changes provoked by cytotoxic agents and more importantly for preclinical testing of new anticancer drugs. We analyzed chromosomal, numerical, and structural changes after development of MDR, alterations in p53 and PTEN, single nucleotide polymorphisms (SNPs) in the mdr1 gene and corresponding protein expression of P-glycoprotein (P-gp) in three human MDR cancer cell lines: non-small cell lung carcinoma NCI-H460/R, colorectal carcinoma DLD1-TxR, and glioma U87-TxR. In addition, we explored how these molecular and phenotypic alterations influence the anticancer effect of new drugs. Cytogenetic analysis showed polyploidy reduction after development of MDR in U87-TxR. Losses of 6q in all resistant cancer cell lines and inactivation of p53 in U87-TxR and PTEN in DLD1-TxR were also revealed. Overexpression of P-gp was observed in all MDR cancer cell lines. We evaluated the anticancer activities and MDR reversal potential of Akt inhibitor GSK690693, Ras inhibitor Tipifarnib, and two P-gp inhibitors (jatrophane diterpenoids). Their effects vary due to the cell-type differences, existence of MDR phenotype, presence of mdr1 SNP, and tumor suppressors' alterations. Tipifarnib and jatrophane diterpenoids significantly sensitized MDR cancer cells to paclitaxel. In conclusion, investigated MDR cancer cells obtained new molecular and cytogenetic characteristics that may serve as potential clinical prognostic markers. In addition, these MDR cancer cell lines present a valuable model for preclinical evaluation of new anticancer agents.
