Methyl salicylate (or methyl 2-hydroxybenzoate), also known as wintergreen oil, is a natural product and is present in white wine, tea, porcini mushroom Boletus edulis, Bourbon vanilla, clary sage, red sage and fruits including cherry, apple, raspberry, papaya and plum. Methyl salicylate is topically used in combination with methanol and under brand name SALONPAS to temporarily relieves mild to moderate aches and pains of muscles and joints associated with: strains, sprains, simple backache, arthritis, bruises. The precise mechanism of action of methyl salicylate is not known, but there is suggested, that it cause dilation of the capillaries thereby increasing blood flow to the area.

Managlinat dialanetil (MB06322 or CS-917) is an inhibitor of fructose 1,6-bisphphosphatase. Managlinat dialanetil is a bisamidate prodrug and its activation requires a two-step enzyme catalyzed reaction. Metabasis Therapeutics Inc in collaboration with Daiichi Sankyo Co Ltd was developing managlinat dialanetil for the potential treatment of type 2 diabetes.

Brifentanii, a potent narcotic analgesic structurally similar to alfentanil, that was studied in clinical trials in the early 1990s. The effects of brifentanil are very similar to those of alfentanil, with strong but short lasting analgesia and sedation, and particularly notable itching and respiratory depression. Side effects of Brifentanii are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening.

Inecalcitol is a calcitriol analog with potential antineoplastic activity patented by a global pharmaceutical company Laboratoire Theramex. Inecalcitol is a potent agonist of vitamin D receptor (VDR). Inecalcitol was shown to be more potent than calcitriol in decreasing tumor cell growth and inducing apoptosis in a number of different model systems including models of breast cancer, prostate cancer, and squamous cell cancer. Importantly, at the doses shown to induce tumor regression in the animal models investigated, Inecalcitol had no major effect on blood calcium levels. In this phase I study, Inecalcitol was found to be well tolerated. Currently, Inecalcitol in combination with the cytotoxic drug, decitabine is undergoing a phase II clinical trial in patients with acute myeloid leukemia who are unfit to receive standard chemotherapy.

Etoxeridine (Carbetidine or Wy2039), a piperidine derivative, is a narcotic analgetic.

Ecalcidene (1-[(1alpha,3beta,5Z,7E,20S)-1,3-dihydroxy-24-oxo-9,10-secochola-5,7,10(19)-trien-24-yl]-piperidine) is a 1-hydroxyvitamin D analogue. Ecalcidene was being developed by Barrier Therapeutics as an oral therapy for psoriasis and acne. However, development has been discontinued.
