Lisofylline [1-(5R-hydroxyhexyl)-3,7-dimethylxanthine] is a unique metabolite of pentoxifylline. Lisofylline inhibited the generation of phosphatidic acid and free fatty acids. Lisofylline blocked the release of pro-inflammatory cytokines in oxidative tissue injury, in response to cancer chemotherapy and in experimental sepsis. Lisofylline regulates immune cell function and autoimmune response by inhibition of IL-12 signalling and cytokine production. Lisofylline may have therapeutic value in the prevention of autoimmune disorders, including Type 1 diabetes, autoimmune recurrence following islet transplantation, and in preservation of beta cell functional mass during islet isolation.

MK-2866 (Gtx-024) is a selective androgen receptor modulator (SARM) for treatment of conditions such as muscle wasting and osteoporosis. It is a non-steroidal agent with anabolic activity designed to work like testosterone, thus promoting and/or maintaining libido, fertility, prostate growth, and muscle growth and strength. Mimicking testosterone's action, this agent may increase lean body mass, thereby ameliorating muscle wasting in the hypermetabolic state of cancer cachexia.

Alvameline is a partial agonist of the M1 mAChR that also displays M2/M3 antagonist effects. It readily crosses the blood-brain barrier. It has an effect profile that makes it of interest to test its ability to counteract bladder overactivity in humans. Behaviorally, alvameline has been shown to significantly improve Morris water maze (MWM) performance in both young and ageimpaired rats. It failed to improve cognition in patients with mild to moderate Alzheimer's disease.

Lysergide (LSD) is a semi-synthetic hallucinogen and is one of the most potent drugs known. Recreational use became popular between the 1960s to 1980s, but is now less common. LSD was first synthesized by Albert Hoffman while working for Sandoz Laboratories in Basel in 1938. Some years later, during a re-evaluation of the compound, he accidentally ingested a small amount and described the first ‘trip’. During the 1950s and 1960s, Sandoz evaluated the drug for therapeutic purposes and marketed it under the name Delysid®. It was used for research into the chemical origins of mental illness. Recreational use started in the 1960s and is associated with the ‘psychedelic period’. LSD possesses a complex pharmacological profile that includes direct activation of serotonin, dopamine and norepinephrine receptors. In addition, one of its chief sites of action is that of compound-specific (“allosteric”) alterations in secondary messengers associated with 5HT2A and 5HT2C receptor activation and changes in gene expression. The hallucinogenic effects of LSD are likely due to agonism at 5HT2A and 5HT2C receptors. LSD is also an agonist at the majority of known serotonin receptors, including 5HT1A, 5HT1B, 5HT1D, 5HT5A, 5HT6 and 5HT7 receptors. During the 1960s, LSD was investigated for a variety of psychiatric indications, including the following: as an aid in treatment of schizophrenia; as a means of creating a "model psychosis"; as a direct antidepressant; and as an adjunct to psychotherapy. LSD is listed in Schedule I of the United Nations 1971 Convention on Psychotropic Substances.

Saracatinib (AZD0530) is an oral, dual inhibitor of c-Src/Abl kinases initially developed by AstraZeneca for the treatment of cancer. The drug was tested for many neoplasms and reached phase III for ovarian cancer (in combination with paclitaxel), however without demonstrating any significant effect. Sarcatinib is also tested in patients with Alzheimer's Disease (Phase II). Its effect on Alzheimer's Disease patients is explained by inhibition of another kinase, Fyn, which is highly expressed in brain.

AST-1306, also known as Allitinib, is an orally active potent, selective, irreversible inhibitor of the HER family of receptor tyrosine kinases. AST-1306 inhibits the enzymatic activities of wild-type epidermal growth factor receptor (EGFR) and ErbB2 as well as EGFR resistant mutant in both cell-free and cell-based systems. AST1306 potently suppressed tumor growth in ErbB2-overexpressing adenocarcinoma xenograft and FVB-2/N(neu) transgenic breast cancer mouse models. Allitinib is in Phase I clinical trial for the treatment of advanced solid tumors. Serious adverse effects detected were: diarrhea, dehydration and hyperbilirubinemia.

Poziotinib is an inhibitor of EGFR tyrosine kinase family. The drug is being tested in phase II of clinical trials for different cancers: breast cancer, lung adenocarcinoma, head and neck squamous cell carcinoma, HER-2 positive advanced gastric cancer (in combination with Paclitaxel and Trastuzumab).

Dovitinib is an orally active small molecule that exhibits potent inhibitory activity against multiple receptor tyrosine kinases (RTK) involved in tumor growth and angiogenesis. Dovitinib strongly binds to fibroblast growth factor receptor 3 (FGFR3) and inhibits its phosphorylation, which may result in the inhibition of tumor cell proliferation and the induction of tumor cell death. In addition, this agent may inhibit other members of the RTK superfamily, including the vascular endothelial growth factor receptor; fibroblast growth factor receptor 1; platelet-derived growth factor receptor type 3; FMS-like tyrosine kinase 3; stem cell factor receptor (c-KIT); and colony-stimulating factor receptor 1; this may result in an additional reduction in cellular proliferation and angiogenesis, and the induction of tumor cell apoptosis. There are several ongoing Phase I/III clinical trials for dovitinib.

Lestaurtinib (CEP-701, KT-5555) is an orally bio-available polyaromatic indolocarbazole alkaloid derived from K-252a. Lestaurtinib is a multi-targeted tyrosine kinase inhibitor which has been shown to potently inhibit FLT3 at nanomolar concentrations in preclinical studies, leading to its rapid development as a potential targeted agent for treatment of AML. Phase I studies have shown lestaturtinib to be an active agent particularly when used in combination with cytotoxic drugs. Currently, Phase II and Phase III studies are underway aiming to establish the future of this agent as a treatment option for patients with FLT3-ITD AML.

BMS-690514 is a potent, reversible oral inhibitor of epidermal growth factor receptor (EGFR/HER-1), HER-2 and -4, and vascular endothelial growth factor receptors (VEGFRs)-1 to -3 offering targeted inhibition of tumour growth and vascularisation in a single agent. Bristol-Myers Squibb was developing BMS 690514, as an oral treatment for cancer. BMS-690514 had being in phase II for the treatment of breast cancer; non-small cell lung cancer, but later these studies were discontinued.
