FIBRACILLIN is a semisynthetic antibacterial agent.
Faropenem medoxomil is an ester prodrug derivative of the beta-lactam antibiotic faropenem. The prodrug form of faropenem offers dramatically improved oral bioavailability and leads to higher systemic concentrations of the drug. Faropenem medoxomil is a broad-spectrum antibiotic that is highly resistant to beta-lactamase degradation. It was under development for the treatment of acute bacterial sinusitis, community-acquired pneumonia, acute exacerbation of chronic bronchitis, and uncomplicated skin and skin structure infections.

Sulopenem is a thiolanylthiopenem derivative patented by American multinational pharmaceutical corporation Pfizer Inc as an antibiotic with broad-spectrum antibacterial activity against most gram-positive and gram-negative bacteria. Sulopenem showed concentration-dependent bactericidal activities against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, and Acinetobacter calcoaceticus. Morphological observation using a phase-contrast microscope revealed that sulopenem induced spherical cell formation with E. coli and K. pneumoniae at lower concentrations and bacteriolysis at higher concentrations. Therapeutic efficacies of sulopenem against systemic infections in mice were almost equal to those of imipenem against Streptococcus pneumoniae.

MK-0767 is a potent hypoglycaemic insulin sensitizer being evaluated by Kyorin with potential as an antidiabetic agent. MK-0767 acts as a dual agonist of the peroxisome proliferator-activated receptors alpha and gamma, induced high-affinity interactions of PPARα and PPARγ with the transcriptional coactivator CBP in vitro. In ob/ob mice, MK-0767 normalized hyperglycemia and hyperinsulinemia with equal or greater potency and efficacy than pioglitazone. Treatment of hamsters with MK-0767 produced substantial reductions in blood cholesterol and triglycerides. In dogs, MK-0767 reduced serum cholesterol levels with a potency more than 10-fold greater than simvastatin. The efficacies of MK-0767 and simvastatin were additive when given together.

Fomidacillin (also known as BRL 36650) is a type of penicillin with antibacterial activity. Studies on volunteers have shown that the drug possessed the bactericidal activity and could be a candidate for the treatment of gram-negative bacillary infections. However, information about the further development of this drug is not available.

Ammonium trichlorotellurate (AS-101) is a synthetic non-toxic tellurium derivative, structurally similar to cisplatin, with immunostimulatory and anti-hair loss properties. Ammonium trichlorotellurate induces production of colony stimulating factor (CSF), interleukin-2 (IL-2), and IL-2 receptors by increasing the calcium ion influx through the cell membrane and subsequently exerts its immunostimulatory effects through the CSF-mediated increase in macrophage/granulocytes. This agent is also a potent inducer of interferon and a spectrum of cytokines such as IL-1, IL-6, and tumor necrosis factor (TNF). In animal studies, ammonium trichlorotellurate exerts its anti-hair loss effect by inducing anagen and obstructing spontaneous catagen via promoting follicular keratinocyte proliferation and interfering with terminal differentiation, respectively. AS-101 suppresses production of HIV-1. It inhibited reverse transcriptase activity and replication of human immunodeficiency virus type 1. RDDP and DDDP activities were impaired by the drug with calculated IC50 value of about 4 uM. Intravenous AS-101 was in trials in patients with HIV infections. AS-101, a small-molecule integrin αvβ3 and VLA-4 inhibitor is being developed by BioMAS in Israel for the treatment of genital warts, age-related macular degeneration and fertility preservation. Phase II clinical trials are ongoing. The drug was also undergoing phase II development in acute myeloid leukaemia, atopic dermatitis, chemotherapy-induced damage, myelodysplastic syndromes, thrombocytopenia, alopecia, psoriasis. However, development for these indications was discontinued.

PF-03463275 is the novel azabicyclic glycine transporter 1 (GlyT1) inhibitor. Ketamine induced hallucinatory-like behaviors that were not reversed by PF-3463275. In contrast, all doses of PF-3463275 alleviated the deficit in spatial working memory induced by ketamine. PF-03463275 causes changes in electroretinogram (ERG) responses in albino rats. There was dose-dependent reduction in the amplitude of the rat ERG oscillatory potentials (OPs) following single subcutaneous administrations of the PF-03463275. Furthermore, the amplitude of OPs was negatively correlated to the concentration of PF-03463275 in the vitreous humor collected from rats immediately following ERG recordings. A slight increase in the amplitude and latency of the a-wave component of the ERG with PF-03463275 treatment was observed. Since the ERG changes occur in our rodent model with PF-03463275 at exposures comparable with those associated with visual disturbance in the clinic, it was proposed that the visual adverse effects reported in healthy volunteers treated with selective GlyT1 inhibitors may represent a retinal class effect. The dose-related GlyT1 occupancy of PF-03463275 is linear. While PF-03463275 did not show evidence of facilitating N-methyl-D-aspartate receptor function in the ketamine assay, it enhanced neuroplasticity in schizophrenia patients. PF-03463275 had been in phase II clinical trial for the treatment of schizophrenia. However, this development was discontinued.

Cetocycline (formerly chelocardin or cetotetrine) is tetracycline derivative with potent antibacterial activity against a number of Gram-positive and Gram-negative multi-resistant pathogens. Cetocycline was found to be more active than tetracycline against many clinical isolates of aerobic gram-negative bacilli, but is less active against staphylococci, and has no activity against Pseudomonas. At low concentrations, like classical tetracyclines, chelocardin induces the proteomic signature for peptidyl transferase inhibition demonstrating that protein biosynthesis inhibition is the dominant physiological challenge. At higher concentrations B. subtilis mainly responds to membrane stress indicating that at clinically relevant concentrations the membrane is the main antibiotic target of chelocardin.
