A marine polycyclic quinone-type metabolite, halenaquinone (HQ), was found to inhibit the proliferation of Molt 4, K562, MDA-MB-231 and DLD-1 cancer cell lines, with IC50 of 0.48, 0.18, 8.0 and 6.76 μg/mL, respectively. It exhibited the most potent activity against leukemia Molt 4 cells. Accumulating evidence showed that HQ may act as a potent protein kinase inhibitor in cancer therapy. To fully understand the mechanism of HQ, we further explored the precise molecular targets in leukemia Molt 4…

Isoaaptamine Induces T-47D Cells Apoptosis and Autophagy via Oxidative Stress
The cytotoxic effect of isoaaptamine is associated with the induction of apoptosis and autophagy through oxidative stress and represents an interesting drug lead in the war against breast cancer.
Antileukemic Scalarane Sesterterpenoids and Meroditerpenoid from Carteriospongia (Phyllospongia) sp., Induce Apoptosis via Dual Inhibitory Effects on Topoisomerase II and Hsp90
The results suggested that the proapoptotic effect of the isolates is mediated through the inhibition of Hsp90 and topoisomerase activities, and the molecular docking analysis suggested that 1 exhibited more binding affinity to N-terminal ATP-binding pocket of HSp90 protein than 17-AAG, a standard Hsp 90 inhibitor.
Synthesis and antitumor evaluation of hybrids of 5,8-dioxo-5,8-dihydroisoquinoline-4-carboxylates and carbohydrates.
The most promising compound, derived from isoquinoline-5,8-dione, containing ribofuranosidyl ring, was selectively active in vitro against H1299 cancer cells, with 1.7-fold higher activity than that of vinorelbine tartrate, suggesting that the glycoconjugate in question may constitute a valuable lead compound to design and synthesize a more active and less toxic derivative with respect to the development of a new antitumor substance.

A large number of HDACs are involved in cancerassociated cell hyperproliferation, invasion, and metastasis, and these enzymes ay also act on non-histone proteins, thereby influencing many fundamental cellular processes, including microtubule dynamics and intracellular transport, metabolism, and aging.


Cracking the Cytotoxicity Code: Apoptotic Induction of 10-Acetylirciformonin B is Mediated through ROS Generation and Mitochondrial Dysfunction
10AB-induced apoptosis is mediated through the overproduction of ROS and the disruption of mitochondrial metabolism, suggesting that ROS overproduction plays a crucial rule in the cytotoxic activity of 10AB.
