Pamicogrel is a cyclooxygenase inhibitor with platelet anti-aggregatory properties which is under development by Kanebo for chronic arterial occlusion. It also has potential in both prophylaxis and treatment of ischemic brain injury. An NDA was submitted in Japan in April 1997. The effects of the drug on platelet aggregation were originally disclosed in EP-00159677, while the later European patent, EP-00560136, claims its use in brain dysfunction induced by hypoxia arising from disturbance of cerebral circulation, such as cerebral hemorrhage or cerebral infarction.

ITROCINONIDE is a synthetic corticosteroid which showed no signs of systemic activity (cortisol depression).

Pinolcaine is 10-methyl-2-substituted piperidine. Pinolcaine is a local anesthetic.

Mivobulin is a synthetic water-soluble colchicine analog with the broad antitumor activity that competitively binds tubulin at the colchicine-binding site and inhibits tubulin polymerization. Cancer cells exposed to Mivobulin isethionate accumulate in the M phase of the cell cycle and subsequently die. Preclinical studies have demonstrated that Mivobulin isethionate is able to cross the blood-brain barrier. Importantly, Mivobulin isethionate demonstrated significant antitumor activity in a broad spectrum of murine and human tumor models that were cross-resistant to vincristine, cisplatin, vinblastine, navelbine, and doxorubicin and in tumor cell lines exhibiting multidrug resistance owing to P-glycoprotein overexpression. In animal studies, the activity of Mivobulin isethionate was largely independent of the route of drug administration but favored a prolonged treatment schedule. Unfortunately, in clinical trials, Mivobulin fail to demonstrate the significant activity

Lorapride is a centrally acting sulfonamide. It has pharmacodynamic properties that are mainly related to ulcer treatment. On the basis of its psychopharmacologic profile, it has no neuroleptic potential, but it does exhibit some psychostimulating components. After oral administration, absorption of lorapride was rapid. The rate of absorption was first order for solution and zero order for capsule.

Adaprolol is a beta-adrenergic antagonist that is being developed as a topical agent to treat glaucoma. Adaprolol demonstrated a safer cardiovascular profile, especially in the population over 70 years old. It was in Phase II clinical trials for the treatment of glaucoma. This research has been discontinued.

Daltroban (also known as BM 13505, SKF 96148), a specific thromboxane A2 receptor antagonist, was studied as an antithrombotic agent. The drug was licensed to Smith Kline Beecham, underwent phase III clinical trials in the UK and Germany as an antithrombotic agent but did not enter clinical trials in the USA. Besides, вaltroban was investigated in patients with an ischemic heart disorder. However, the development of daltroban has been discontinued.

CYT997 (Lexibulin) is a wholly synthetic compound that possesses highly potent cytotoxic activity in vitro through inhibition of microtubule polymerization. CYT997 (Lexibulin) is a potent microtubule polymerization inhibitor with IC50 of 10-100 nM in cancer cell lines. CYT997 (Lexibulin) blocks the cell cycle at the G(2)-M boundary, and Western blot analysis indicates an increase in phosphorylated Bcl-2, along with increased expression of cyclin B1. Caspase-3 activation is also observed in cells treated with CYT997 (Lexibulin) along with the generation of poly(ADP-ribose) polymerase. The compound possesses favorable pharmacokinetic properties, is orally bioavailable, and is efficacious per os in a range of in vivo cancer models, including some refractory to paclitaxel treatment. CYT997 (Lexibulin) exhibits vascular disrupting activity as measured in vitro by effects on the permeability of human umbilical vein endothelial cell monolayers, and in vivo by effects on tumor blood flow. CYT997 (Lexibulin) possesses a useful combination of pharmacologic and pharmacokinetic properties having considerable potential as a novel anticancer agent. Lexibulin was being developed by YM BioSciences as a vascular-disrupting agent (VDA) for the potential treatment of cancer, it was in phase II development on YM BioSciences ' pipeline. It appears that the development of lexibulin has been discontinued.

Clorisamine is an antihistamine drug developed by Schering in the 1970s. The drug was evaluated in phase 1 clinical trial on healthy volunteers. The results show that in a therapeutic dose of 2 mg the drug did not have any effects which might lead to an impairment of driving ability.

Ethylmethylthiambutene is a potent analgesic compatible with morphine. It possesses addiction liability similar to that of morphine.
