Talabostat is a prolineboronate ester derivative patented by Boehringer Ingelheim Pharmaceuticals, Inc. as an antineoplastic agent. Talabostat inhibits dipeptidyl peptidases, such as fibroblast activation protein (FAP), resulting in the stimulation of cytokine and chemokine production and specific T-cell immunity and T-cell dependent activity. Talabostat has been shown to cause caspase-1 activation and IL-1β induction in macrophages, which in turn causes upregulation of the cytokines and chemokines that characterize the responses to talabostat, both in vitro and in tumor-bearing mice. Talabostat may also stimulate the production of colony stimulating factors, such as granulocyte colony stimulating factor (G-CSF), resulting in the stimulation of hematopoiesis. In clinical trials, the combination of talabostat and cisplatin was well tolerated compared to historical data using cisplatin alone. The most frequent adverse events were nausea, vomiting, fatigue, anemia, edema, and constipation. Unfortunately was no evidence that Talabostat enhanced the clinical activity of other anticancer drugs and further development was discontinued.

Talnetant (SB-223412) is a selective, orally active neurokinin 3 receptor antagonist and is under development for the potential treatment of several disorders, including irritable bowel syndrome, schizophrenia, chronic obstructive pulmonary disease, cough, overactive bladder and urinary incontinence. The most common adverse effects were headache, fatigue, and nausea.

BROTIANIDE is salicylanilide derivative used to treat fascioliasis in sheep. A dose of 7 mg/kg of brotianide shows 91-99% activity against 7-14 weeks old flukes; however, its activity against 6 weeks old flukes is weak (50-90%). It also possesses 85-90% activity against paramphistomes in sheep and cattle. The maximum tolerated dose of brotianide is 27 mg/kg in sheep.

Xenbucin is an antihyperlipidemic agent. Information about the current use of this agent is not available.

Lexipafant is a platelet-activating factor (PAF) antagonist. It was hypothesized that the substance could beneficially affect the cognitive performance of HIV infected people. Lexipafant was as tolerable as placebo. At week 6 and week 10 after baseline evaluations, the lexipafant group showed trends toward improvement on the Rey Auditory Verbal Learning test as well as the timed gait test. A phase IIa placebo-controlled study reported that lexipafant was not effective in patients with severe ulcerative colitis receiving corticosteroids. Two lexipafant treated patient had adverse events: severe influenza-like symptoms in one and hypotension with iliac artery thrombosis in one. The clinical trials of lexipafant in the treatment of acute pancreatitis were undertaken with considerable optimism. There was a significant reduction in the incidence of organ failure and in total organ failure score at the end of medication (72 h).

Trifosmin is used for the preparation of 99mTc-labeled myocardial perfusion imaging agents.

Famprofazone, a nonsteroidal anti-inflammatory agent, is found in a multi-ingredient medication (Gewodin) used for pain relief. It is available over-the-counter in Taiwan. Famprofazone transforms to methamphetamine (MA) and amphetamine (AM) following administration, which is responsible for the side effects of the drug. For example, famprofazone user might be interpreted as an illicit MA abuser in Taiwan because the user's urine tested positive for MA.

Resiquimod is an imidazoquinolinamine and Toll-like receptor (TLR) agonist with potential immune response modifying activity. Resiquimod exerts its effect through the TLR signaling pathway by binding to and activating TLR7 and 8 mainly on dendritic cells, macrophages, and B-lymphocytes. This induces the nuclear translocation of the transcription activator NF-kB as well as activation of other transcription factors. This may lead to an increase in mRNA levels and subsequent production of cytokines, especially interferon-alpha (INF-a) and other cytokines, thereby enhancing T-helper 1 (Th1) immune responses. In addition, topical application of resiquimod appears to activate Langerhans' cells, leading to an enhanced activation of T-lymphocytes. Resiquimod is used as a topical gel[1] in the treatment of skin lesions[2] such as those caused by the herpes simplex virus[3][4] and cutaneous T cell lymphoma. Due to its immunostimulatory activity, this agent may potentially be used as a vaccine adjuvant.

Phenylthilone is an anticonvulsant, hypnotic and spasmolytic agent.
