As our ongoing work on lathyrane diterpenoid derivatization, three series of lathyrane diterpenoid derivatives were designed and synthesized based combination principles, including pyrazole, thiazole and furoxan moieties. Biological evaluation indicated t

To get chelidonine derivatives with enhanced antiproliferative activity and selectivity, a series of nitric oxide donating derivatives (10a-f and 11a-j) were designed, synthesized and biologically evaluated. Compared with chelidonine, these compounds exhibited lower IC50 values against human hepatoma cells HepG2, breast cancer cells MCF-7, colon cancer cells HCT-116, as well as leukemia cells K562. Compound 11j displayed the strongest antiproliferative activity with IC50 values of 3.91, 6.90, 4.36 and 1.12 μM against the above four cells, respectively. Nevertheless, it showed an IC50 value >40 μM against human peripheral blood mononuclear cells (PBMCs), which demonstrated high selectivity between normal and cancer blood cells. In further mechanism studies, 11j showed the capability to induce K562 cells apoptosis, S phase cell cycle arrest and mitochondrial membrane potential disorder. Besides, 11j was found to be effective in promoting the expression of proapoptotic protein Bad and suppressing the expression of anti-apoptotic proteins Bcl-xL, catalase, survivin, claspin and clusterin.

A series of novel hybrids 10a-m were designed and synthesized by coupling phenylsulfonyl furoxans with gemcitabine through various diols or alcohol amine linkers, and their biological activities were evaluated in vitro. Most of the hybrids exhibited good to moderate anti-tumor activities, which are associated with NO release. In particular, hybrid 10e showed excellent anticancer activities which were more potent than or comparable to gemcitabine. However, inhibition of nucleoside transport only significantly decreased the inhibitory rates of gemcitabine against HepG2 cells but not 10e, and the inhibitory rates of 10e were partially reduced by pre-treatment with hemoglobin, demonstrating that the anti-tumor activity of 10e might result from the synergic effect of high levels of NO production and gemcitabine fragment. In addition, compound 10ecould apparently induce cell apoptosis by regulating apoptotic relative proteins. Therefore, our novel findings provide a proof of principle in the design of new furoxan/gemcitabine hybrids for the intervention of human cancers.
