Development of hybrid drug candidates is well known strategy for designing antitumor agents. Herein, a novel class of nitric oxide donating cucurbitacin inspired estrone analogs (NO-CIEAs) were designed and synthesized as multitarget agents. Synthesized analogs were initially evaluated for their anti-hepatocellular carcinoma activities. Among the tested analogs, NO-CIEAs 17 and 20a exhibited more potent activity against HepG2 cells (IC50 = 4.69 and 12.5 μM, respectively) than the reference drug Erlotinib (IC50 = 25 μM). Interestingly, NO-CIEA 17 exerted also a high potent activity against Erlotinib-resistant HepG2 cell line (HepG2-R) (IC50 = 8.21 μM) giving insight about its importance in drug resistance therapy. Intracellular measurements of NO revealed that NO-CIEAs 17 and 20a showed a significant increase in NO production in tumor cells after 1 h of incubation comparable to the reference prodrug JS-K. Flow cytometric analysis showed that both NO-CIEAs 17 and 20a mainly arrested the HepG2 cells in the G0/G1 phase. Also, In-Cell Based ELISA screening showed that NO-CIEA 17 resulted in a potential inhibitory activity towards the EGFR and MAPK (25% and 29% inhibition compared to untreated control cells, respectively). This data suggests the binding ability of NO-CIEA 17 to the EGFR and ERK to be well correlated along with the docking and cellular studies. Also, treatment of HepG2-R cells with NO-CIEA 17 showed a potential reduction of MRP2 expression in a dose dependent manner providing a significant impact on the chemotherapeutic resistance. Overall, the current study provides a potential new approach for the discovery of a novel antitumor agent against HCC.

The invention relates to an aurovertin B derivative and a preparation method of the aurovertin B derivative, and application of the aurovertin B derivative in preparation of a medicine for treating triple-negative breast cancer. Compared with aurovertin B, the aurovertin B derivative disclosed by the invention has the advantages that the water solubility of the compound is improved, the bioavailability can be improved, and the preparation is convenient to prepare. Meanwhile, compared with aurovertin B, the aurovertin B derivative disclosed by the invention has the advantages that the derivative has obvious dose dependence, the toxicity of the compound to normal cells is reduced, and the druggability of the compound is improved. The aurovertin B derivative disclosed by the invention has a very strong inhibition effect on proliferation of triple-negative breast cancer cells, and the activity of the aurovertin B derivative is stronger than that of paclitaxel serving as a clinical drug.
