Ozanimod (previously known as RPC-1063) is a selective immune-inflammatory modulator of the G protein-coupled receptors sphingosine 1-phosphate 1 and 5, which are part of the sphingosine 1-phosphate (S1P) receptor family. Treatment with S1P receptor modulators interferes with S1P signaling and blocks the response of lymphocytes (a type of white blood cell) to exit signals from the lymph nodes, sequestering them within the nodes. The result is a downward modulation of circulating lymphocytes and anti-inflammatory activity by inhibiting cell migration to sites of inflammation. Ozanimod is currently in phase III clinical trials for the treatment of relapsing multiple sclerosis (RMS) and ulcerative colitis, and also in phase II clinical trials to determine whether it is effective in the treatment of Crohn's disease.

Lumateperone (ITI-722/ITI-007) is a dual 5HT2A receptor antagonist/dopamine phosphoprotein modulator (DPPM) for the treatment of schizophrenia. It is an orally available compound which combines potent 5HT2A receptor antagonism with cell-type-specific modulation of phosphoprotein pathways downstream of dopamine receptors. Lumateperone was developed by Intra-Cellular Therapies, Inc., and is being evaluated for the treatment of schizophrenia and bipolar depression. In 3 efficacy studies in patients with acute schizophrenia, lumateperone was well-tolerated with a favorable safety profile, and in 2 studies of 3 demonstrated significantly superior efficacy over placebo.

Oxcarbazepine and its active metabolite (10,11-dihydro-10-hydroxy-carbazepine, MHD) have been effective in animal models of epilepsy that generally predict efficacy in generalized tonic-clonic seizures and partial seizures in humans. The pharmacokinetic profile of oxcarbazepine is less complicated than that of carbamazepine, with less metabolism by the cytochrome P450 system, no production of an epoxide metabolite, and lower plasma protein binding. The clinical efficacy and tolerability of oxcarbazepine have been demonstrated in trials in adults, children, and the elderly. The pharmacological activity of oxcarbazepine is primarily exerted through the 10-monohydroxy metabolite (MHD) of oxcarbazepine. The precise mechanism by which oxcarbazepine and MHD exert their antiseizure effect is unknown; however, in vitro electrophysiological studies indicate that they produce blockade of voltage-sensitive sodium channels, resulting in stabilization of hyperexcited neural membranes, inhibition of repetitive neuronal firing, and diminution of propagation of synaptic impulses. These actions are thought to be important in the prevention of seizure spread in the intact brain. In addition, increased potassium conductance and modulation of high-voltage activated calcium channels may contribute to the anticonvulsant effects of the drug.

Fenofibrate is a drug of the fibrate class. It is mainly used to reduce cholesterol levels in people at risk of cardiovascular disease. It’s used as adjunctive therapy to diet to reduce elevated LDL-C, Total-C,Triglycerides and Apo B, and to increase HDL-C in adult patients with primary hypercholesterolemia or mixed dyslipidemia (Fredrickson Types IIa and IIb). Fenofibrate is a fibric acid derivative, a prodrug comprising fenofibric acid linked to an isopropyl ester. Fenofibrate is rapidly hydrolyzed after oral ingestion to its pharmacologically active form, fenofibric acid. The effects of fenofibric acid seen in clinical practice have been explained in vivo in transgenic mice and in vitro in human hepatocyte cultures by the activation of peroxisome proliferator activated receptor α (PPARα). It lowers lipid levels by activating peroxisome proliferator-activated receptor alpha (PPARα). PPARα activates lipoprotein lipase and reduces apoprotein CIII (an inhibitor of lipoprotein lipase activity), which increases lipolysis and elimination of triglyceride-rich particles from plasma. The resulting fall in triglycerides produces an alteration in the size and composition of LDL from small, dense particles (which are thought to be atherogenic due to their susceptibility to oxidation), to large buoyant particles. These larger particles have a greater affinity for cholesterol receptors and are catabolized rapidly. PPARα also increases apoproteins AI and AII, reduces VLDL- and LDL-containing apoprotein B, and increases HDL-containing apoprotein AI and AII.Fenofibrate also reduces serum uric acid levels in hyperuricemic and normal individuals by increasing the urinary excretion of uric acid. Fenofibrate also has an off-label use as uricosuric therapy in people who have gout.

Nabumetone is a naphthylalkanone. Is is a non-selective prostaglandin G/H synthase (a.k.a. cyclooxygenase or COX) inhibitor that acts on both prostaglandin G/H synthase 1 and 2 (COX-1 and -2). Prostaglandin G/H synthase catalyzes the conversion of arachidonic acid to prostaglandin G2 and prostaglandin G2 to prostaglandin H2. Prostaglandin H2 is the precursor to a number of prostaglandins involved in fever, pain, swelling, inflammation, and platelet aggregation. The parent compound is a prodrug that undergoes hepatic biotransformation to the active compound, 6-methoxy-2-naphthylacetic acid (6MNA). The analgesic, antipyretic and anti-inflammatory effects of NSAIDs occur as a result of decreased prostaglandin synthesis. The parent compound is a prodrug, which undergoes hepatic biotransformation to the active component, 6-methoxy-2-naphthylacetic acid (6MNA), that is a potent inhibitor of prostaglandin synthesis, most likely through binding to the COX-2 and COX-1 receptors. Nabumetone is used for acute and chronic treatment of signs and symptoms of osteoarthritis and rheumatoid arthritis. Nabumetone has been developed by Beecham. It is available under numerous brand names, such as Relafen, Relifex, and Gambaran.

Methylprednisolone is a prednisolone derivative with similar anti-inflammatory and immunosuppressive action. It is adjunctive therapy for short-term administration in rheumatoid arthritis. It is indicated in the following conditions: endocrine disorders, rheumatic disorders, collagen diseases, allergic states etc. Methylprednisolone is marketed in the USA and Canada under the brand names Medrol and Solu-Medrol. Methylprednisolone is a GR receptor agonist.

Dydrogesterone is an orally active progestogen which acts directly on the uterus, producing a complete secretory endometrium in an estrogen-primed uterus. At therapeutic levels, dydrogesterone has no contraceptive effect as it does not inhibit or interfere with ovulation or the corpus luteum. Furthermore, dydrogesterone is non-androgenic, non-estrogenic, non-corticoid, non-anabolic and is not excreted as pregnanediol. Dydrogesterone helps to regulate the healthy growth and normal shedding of the uterus lining. Therefore, it may be useful in the treatment of menstrual disorders such as absent, irregular or painful menstrual periods, infertility, premenstrual syndrome and endometriosis. Dydrogesterone works by regulating the healthy growth and normal shedding of the womb lining by acting on progesterone receptors in the uterus. Used to treat irregular duration of cycles and irregular occurrence and duration of periods caused by progesterone deficiency. Also used to prevent natural abortion in patients who have a history of habitual abortions. Dydrogesterone was first introduced to the market in 1961, and is currently approved in over 100 countries world-wide. Banned in the USA and wthdrawn from the UK, but still used in other countries.

Norethynodrel is a steroidal progestin of the 19-nortestosterone group and an isomer of norethisterone. Norethynodrel is a progesteron agonist with very weak estrogenic activiry. Noretynodrel was introduced in 1957 in Enovid, a combination formulation of noretynodrel and mestranol, for the treatment of gynecological and menstrual disorders.A few years later, in May 1960, Enovid was also approved as the first oral contraceptive.

Befunolol is a beta-adrenergic receptor blocker approved in Japan for the treatment of open-angle glaucoma. The current drug status is unknown.

Tibolone (brand name Livial, Tibofem), also known as 7α-methylnoretynodrel, is a synthetic steroid drug with estrogenic, progestogenic, and weak androgenic actions which was introduced in 1988 and is used widely in Europe, Asia, Australasia, and, with the exception of the United States (where it is not available), the rest of the world. It is used mainly for treatment of endometriosis, as well as for the treatment of symptoms resulting from the natural or surgical menopause in post menopausal women. Women above 60 years of age should only start with LIVIAL treatment when they are intolerant of or contraindicated for other medicinal products approved for the treatment of oestrogen deficiency symptoms. Tibolone is used for the prevention of bone mineral density loss in postmenopausal women at high risk of future osteoporotic fractures who are intolerant of, or contraindicated for, other medicinal products approved for the prevention of bone mineral density loss. Tibolone has similar or greater efficacy compared to older hormone replacement drugs, but shares a similar side effect profile. It has also been investigated as a possible treatment for female sexual dysfunction. Tibolone is a 19-nortestosterone derivative and is related structurally to other 19-nortestosterone progestins. It is the 7α-methyl derivative of noretynodrel. Tibolone possesses a complex pharmacology. Its two major active metabolites, 3α-hydroxytibolone and 3β-hydroxytibolone, act as potent, fully activating agonists of the estrogen receptor (ER), with a high preference for ERα. Tibolone and its metabolite Δ-tibolone act as agonists of the progesterone and androgen receptors, while 3α-hydroxytibolone and 3β-hydroxytibolone, conversely, act as antagonists of these receptors. Lastly, tibolone, 3α-hydroxytibolone, and 3β-hydroxytibolone act as antagonists of the glucocorticoid and mineralocorticoid receptors, with preference for the mineralocorticoid receptor.
