Crenolanib is an orally active, highly selective, small molecule, next generation inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine kinase. Crenolanib, manufactured by Arog Pharmaceuticals in Dallas, is taken orally with chemotherapy. The compound is currently being evaluated for safety and efficacy in clinical trials for various types of cancer, including acute myeloid leukemia (AML), gastrointestinal stromal tumor (GIST), and glioma. Crenolanib is an orally bioavailable, selective small molecule inhibitor of type III tyrosine kinases with nanomolar potencies against platelet-derived growth factor receptors (PDGFR) (isoforms PDGFRα and PDGFRβ) and Fms-related tyrosine kinase 3 (FLT3). Besides PDGFR and FLT3, crenolanib does not inhibit any other known receptor tyrosine kinase (RTK) (e.g. VEGFR and FGFR) or any other serine/threonine kinase (e.g., Abl, Raf) at clinically achievable concentrations. Preclinical trials have shown Crenolanib to be active in inhibiting both wild-type and mutant FLT3. Crenolanib is cytotoxic to the FLT3/ITD-expressing leukemia cell lines Molm14 and MV411, with IC50s of 7 nM and 8 nM, respectively. In immunoblots, crenolanib inhibited phosphorylation of both the wild-type FLT3 receptor (in SEMK2 cells) and the FLT3/ITD receptor (in Molm14 cells) in culture medium with IC50s of 1-3 nM. Importantly, the IC50 of crenolanib against the D835Y mutated form of FLT3 was 8.8 nM in culture medium. Furthermore, crenolanib had cytotoxic activity against primary samples that were obtained from patients who had developed D835 mutations while receiving FLT3 TKIs. In vitro, the IC50 of crenolanib for inhibition of FLT3/ITD in plasma was found to be 34 nM, indicating a relatively low degree of plasma protein binding. From pharmacokinetic studies of crenolanib in solid tumor patients, steady state trough plasma levels of roughly 500 nM were found to be safe and tolerable, suggesting that crenolanib could potentially inhibit the target in vivo. Crenolanib has no significant activity against c-KIT, which may be an advantage in that myelosuppression can be avoided.1Furthermore, there was no evidence of QTc prolongation in patients treated with crenolanib. In summary, crenolanib offers a number of advantages over other FLT3 TKIs. Clinical trials of crenolanib in AML patients with FLT3 activating mutations are being planned.

Locicortolone is an anti-inflammatory and antiallergic synthetic glucocorticoid. It has high glucocorticoid cytoplasmic receptor binding affinity in vitro (more than four times higher than dexamethasone) but comparable to dexamethasone relative TAT (tyrosine aminotransferase induction) activity. It has six times lower binding affinity to mineralocorticoid receptor in comparison to dexamethasone.

Telapristone acetate, a selective progesterone receptor modulator (SPRM), was developed for the long-term treatment of symptoms associated with endometriosis and uterine fibroids. It is known, that the progesterone is a steroid hormone that plays an important role in the breast. Deregulation of the progesterone-signaling pathway is implicated in the formation, development, and progression of breast cancer. Thus, the telapristone acetate is studied in phase II clinical trial in stage I-II primary breast cancer. Besides, telapristone acetate participated in phase III clinical trials in pre-menopausal anemic women with symptomatic uterine fibroids. However, FDA terminated these studies because of the safety.

Among the naturally occurring trichothecenes in food and feed, T-2 toxin is a cytotoxic fungal secondary metabolite produced by various species of Fusarium. Following ingestion, T-2 toxin causes acute and chronic toxicity and induces apoptosis in the immune system and fetal tissues. T-2 toxin is usually metabolized and eliminated after ingestion, yielding more than 20 metabolites. Consequently, there is a possibility of human consumption of animal products contaminated with T-2 toxin and its metabolites. The molecular mechanism of inhibition of protein synthesis may be the high affinity of T-2 toxin for the 60S ribosomal subunit.

Oxi0-4503 (now known as combretastatin A1 phosphate), a diphosphate prodrug of combretastatin A1, was developed by Mateon therapeutics as a second-generation, dual-mechanism vascular disrupting agent from the combretastatin family. On November 21, 2012, Oxi-4503 has been granted orphan designation by the US Food and Drug Administration for the treatment of acute myelogenous leukemia. It is known that the orphan drug designation qualifies a company for several benefits, including the potential for market exclusivity, development grants, and tax credits. Oxi0-4503 is currently participating in phase I/II clinical trial the treatment of patients with acute myelogenous leukemia or myelodysplastic syndrome. In addition, phase I clinical trial was successfully completed where was studied the safety of Oxi0-4503 in patients with advanced solid tumors.

Osaterone acetate (previously known as TZP-4238), a synthetic steroidal anti-androgen agent. Osaterone acetate is used in veterinary in Europe in the treatment of benign prostatic hyperplasia (BPH) in male dogs. Osaterone acetate inhibits the effects of an excess of male hormone (testosterone) through various mechanisms. It competitively prevents the binding of androgens to their prostatic receptors and blocks the transport of testosterone into the prostate. Osaterone acetate was also investigated in Japan in the treatment of prostate cancer and BPH and, in addition, was studied in postmenopausal osteoporosis in humans. However, these studies were discontinued.

Buparlisib (NVP-BKM12), a dimorpholino pyrimidine derivative, is a selective pan class I phosphatidylinositol-3 kinase (PI3K) inhibitor for treating cancer. It penetrates the blood-brain barrier and has a potential as a glioma treatment. NVP-BKM120 inhibits PI3K activity by binding to the ATP binding cleft of this enzymes and was tested against class I PI3K and other kinases using an ATP depletion (Kinase-Glo) assay. The compound was shown to be active against P110 α, β, γ and δ. The inhibition of the PI3K signaling pathways leads to different forms of cell death on the basis of p53 statuses. Buparlisib demonstrated its activity in human glioblastoma (GBM) cells in vitro and in vivo and is in clinical trials for solid tumors including GBM.
