Topotecan hydrochloride, a topoisomerase I inhibitor, capable of inhibiting tumoral growth in animal models of retinoblastoma. Topotecan hydrochloride liposomes loaded CS/β-GP hydrogel could become a potential formulation for improving the antitumor efficacy of Topotecan hydrochloride. Topotecan hydrochloride is a pyranoindolizinoquinoline. It has a role as an antineoplastic agent and an EC 5.99.1.2 (DNA topoisomerase) inhibitor. It contains a topotecan.

2-Hydroxy-6-tridecylbenzoic acid is a hydroxybenzoic acid. It is functionally related to a salicylic acid.

Cephalotaxine is a benzazepine alkaloid isolated from Cephalotaxus harringtonia. It is a secondary alcohol, an organic heteropentacyclic compound, a benzazepine alkaloid, a benzazepine alkaloid fundamental parent, an enol ether, a tertiary amino compound and a cyclic acetal. Cephalotaxine is an antiviral as well as antitumor agent. It is useless for the treatment of infection by flaviviruses, but potentially useful in combined therapy against hepatitis B.

Isoformononetin shows fungitoxic activity against Cladosporium sphaerospermum; it also has immunomodulatory activity, it inhibits the differentiation of Th17 cells and B-cell lymphopoesis to promote osteogenesis in estrogen-deficient bone loss conditions. Isoformononetin reverses bone loss in osteopenic rats and exerts bone anabolic action by preventing osteoblast apoptosis. Isoformononetin is a methoxyisoflavone that is isoflavone substituted at positions 4' and 7 by hydroxy and methoxy groups respectively. It has a role as a metabolite, a bone density conservation agent and an apoptosis inhibitor. It is a member of 7-methoxyisoflavones and a hydroxyisoflavone. It is functionally related to a daidzein.

Cyclopamine is a Hedgehog (Hh) pathway antagonist with an IC50 of 46 nM in the Hh cell assay, it can increase levels of p27, and decreases both expression of IGF-II and activation of Akt in PC-3 prostate cancer cells. Cyclopamine as a novel, potent inhibitor of human breast cancer proliferation and estrogen responsiveness that could potentially be developed into a promising therapeutic agent for the treatment of breast cancer. Cyclopamine also can suppress the growth of leukemia and lymphoma cells. Cyclopamine is a member of piperidines. It has a role as a glioma-associated oncogene inhibitor.

Jervine exhibits cytotoxic activity against human tumor cell lines A549, PANC-1, SW1990 and NCI-H249, it induces COX-2 overexpression in human erythroleukemia cells. Jervine exhibits potent toxic effects against Colorado potato beetle.
