Aderbasib, also known as INCB007839, is an orally bioavailable low nanomolar hydroxamate-based inhibitor of the ADAM (A Disintegrin And Metalloprotease) family of multifunctional membrane-bound proteins with potential antineoplastic activity. Aderbasib represses the metalloproteinase "sheddase" activities of ADAM10 and ADAM17, which may result in the inhibition of tumor cell proliferation. In preclinical studies, Aderbasib with lapatinib prevented the growth of HER-2/neu–positive BT474-SC1 human breast cancer xenografts in vivo. Aderbasib was being developed by Incyte as a potential adjunctive treatment for metastatic breast cancer. Aderbasib in combination with trastuzumab increased the response rate in HER2 positive metastatic breast cancer patients with advanced disease, relative to historical controls (50% versus 15–35%). INC7839 also improved progression-free survival in a subset of the patients expressing the p95 fragment of HER2. Aderbasib development was halted in 2011 after positive findings from Phase II trials were contradicted by further research. Aderbasib is currently being tested in combination with rituximab for diffuse large B cell non-Hodgkin lymphoma.

Lozilurea (N' -3-chlorobenzyl-N'-ethylurea, ITA 312) has shown marked anti-ulcer activity. It has shown itself to be active against chemically and neurogenically induced gastric and duodenal lesions in various experimental animal models. It has no major anti-secretory action. The experimental data obtained suggest that the mechanism of action of lozilurea consists in increasing the protective function of the mucus barrier. It increased gastric levels of hexosamines and mucoproteins. In the screening trials carried out in order to detect the side effects of lozilurea, it has shown sedative, antipyretic and vasodilatory actions.

Tresperimus is a new stable immunosuppressive analog of 15-deoxyspergualin (DSG) obtained by organic chemical synthesis. It was initially developed as an antitumor agent. Tresperimus has been designed to be chemically stable in aqueous solution. Tresperimus controlled alloreactivity in a fully major histocompatibility complex (MHC) mismatched rat cardiac transplant model and also induced donor-specific long-lasting unresponsiveness. Posttransplant tresperimus therapy effectively protected mice from lethal graft-versus-host disease (GVHD) in a dose-related manner. It has been shown to suppress graft rejection as efficiently as cyclosporine A. Indeed, a short course of tresperimus has similar or better effects compared to the effects of cyclosporine in bone marrow, cardiac, and skin transplant models. Prevention of rejection is related to the induction of donor-specific tolerance without affecting immunity to third-party antigens. In addition, CD4+ T-cells from tresperimus-treated animals can transfer donorspecific tolerance to naive animals, an effect not seen with cyclosporine or other traditional immunosuppressive drugs. The mechanism by which tolerance is induced is not clear. Tresperimus binds to Hsc70, a heat shock protein– chaperoned peptide that, among other effects, inhibits nuclear localization of nuclear factor (NF)-kB, which is required for CD40 and CD28 ligation signaling in antigen-presenting cells, an important early step in T-cell costimulation. Locally administered tresperimus appears to be a potential immunosuppressive agent in the management of intraocular inflammation. Tresperimus had been in phase III clinical trial for the treatment of graft-versus-host disease. However, this development was discontinued.

Cinalukast (Ro 24-5913 ) is a selective leukotriene D4 receptor antagonist originated by Roche. Cinalukast inhibits the actions of Leukotriene D4 at the cysteinyl leukotriene receptor, CysLT1, in the human airway. Leukotriene receptor occupation has been correlated with the pathophysiology of asthma, including airway edema and altered cellular activity associated with the inflammatory process, which contributes to the signs and symptoms of asthma. Cinalukast had been investigated for the treatment of asthma, but that study was discontinued.

Cinflumide is a cinnamamide derivative manufactured by Burroughs Wellcome Co. It is claimed to be a CNS voluntary muscle relaxant.

Metazide (RO 2-4969), a isonicotinic acid hydrazide derivative, is a tuberculostatic agent. Metazid causes damage to the membrane of Mycobacterium tuberculosis, inhibits metabolic and oxidative processes, inhibits the synthesis of nucleic acids, inhibiting the proliferation of bacteria inside and outside the cell. It has been used in the treatment of all forms and localizations of active tuberculosis in adults and children

Mesulfamide is a synthetic antibacterial agent.

Tetronasin is a furanone derivative patented by Imperial Chemical Industries Ltd. as antibiotic and feed additive for ruminants. Tetronasin acts as divalent antiporter that binds preferentially with Ca2+ or Mg2+ and inhibits anaerobic fungi and Gram-negative bacteria in vitro.

Mafoprazine is a phenylpiperazine derivative exerting postsynaptic dopamine D2 receptor blocking activity and alpha-adrenergic activity (alpha 1 receptor blocking activity and alpha 2 receptor stimulating activity). In animal models, mafoprazine demonstrated antipsychotic, aggression-inhibiting and cataleptogenic actions.
