Bryostatin 1 is a macrocyclic lactone which can be isolated from the marine bryozoan, Bugula neritina. The effects of bryostatin 1 are attributed to its ability to selectively modulate the activity of two of the three subgroups of protein kinase C (PKC) isozymes. PKC isozymes are divided into three subgroups which differ in their molecular structures and co-factor requirements: classical PKC (cPKC), novel PKC (nPKC), and atypical PKC (aPKC). Bryostatin-1 modulates nPKC activity independent of a Ca2+ signaling. It activates cPKC only when associated with Ca2+ signaling. And, aPKC activity is not sensitive to bryostatin-1 administration. Ca2+ signals play an important role in synaptic transmission and information processing which creates a biological environment where Bryostatin-1 possesses a unique action profile. Bryostatin-1 will not affect cPKC activity in neurons which are not functioning as an active part of the signaling processing circuit with significant Ca2+influx and intracellular Ca2+ release. Bryostatin 1 is in phase II clinical trials for investigation as an anticancer agent; specifically for treatment of metastatic or recurrent head and neck cancer, ovarian epithelial cancer that has not responded to previous chemotherapy, and myelodysplastic syndrome. Bryostatin 1 has also generated interest as an investigational compound for the treatment of Alzheimer's disease.

Lerimazoline is a sympathomimetic drug that belongs to the imidazoline class of compounds, and is used as a nasal decongestant. Lerimazoline displayed high affinity for the 5-HT1A receptor and for the 5-HT1D receptor. Binding affinity estimates for α1-adrenoceptor, 5-HT2A, and D2 receptors were more than ten times lower. The mechanism of vasoconstrictor action of lerimazoline encompasses both, the activation of 5-HT2A, and to a lesser degree α1 -adrenergic receptors. These results also suggest that lerimazoline is an “atypical” decongestant. It inhibits secretion of nasal mucus. Lerimazoline causes hypertension.

Sodium taurodeoxycholate is a bile salt-related, anionic detergent used for isolation of membrane proteins including inner mitochondrial membrane proteins. It is formed by the conjugation of ursodeoxycholic acid (UDCA) with taurine. Sodium taurodeoxycholate and ursodeoxycholic acid are major constituents of black bear bile, which has been used in traditional Chinese medicine for thousands of years. Bear bile was historically employed to treat a number of diseases including jaundice, summer diarrhea, abdominal pain due to hepatobiliary diseases and gastric malfunction, biliary ascariasis, infectious skin diseases, the common cold, intestinal worms, and inflammation of the throat. Sodium taurodeoxycholate has been shown to inhibit apoptosis by modulating mitochondrial membrane perturbation and pore formation, B cell lymphoma 2 (Bcl-2)-associated protein X (BAX) translocation, cytochrome c release, and caspase activation. Sodium taurodeoxycholate inhibits amyloid beta (Ab)-induced apoptosis and attenuates the endoplasmic reticulum (ER) stress, which are thought to be key components of the pathological process in certain diseases. In clinical studies, Sodium taurodeoxycholate is shown to be very safe with oral administration of 1500 mg/day for up to 6 months. In a more recent clinical study, a dose of 1750 mg/day for up to 4 weeks was well tolerated in healthy obese persons. One of the major adverse effects of Sodium taurodeoxycholate is diarrhea. Based on the related information from ursodeoxycholic acid, other gastrointestinal side effects are possible including abdominal pain, flatulence, nausea, dyspepsia, and anorexia.

ADL5859 (or ADL-5859) is Adolor Corporation developed a novel, oral compound that targets the delta opioid receptor. Delta receptor agonists are thought to offer benefits over other approaches to the management of pain. ADL-5859 was in the phase II of clinical trial for the treatment of neuropathic pain, acute pain, and pain due to osteoarthritis of the knee and for patients with osteoarthritis. Further development of this drug as potential pain treatments was discontinued.

Icaritin is a monoprenylated favonol with 4′-methoxyl from Epimedium Genus. It has been documented to have osteoblastic and neuroprotective activities. It can reduce the incidence of steroid-associated oesteonecrosis in rabbit with inhibition of both intravascular thrombosis and extravascular lipid deposition for maintaining the integrity of intraosseous vasculature. Icaritin shows anti-infammatory activity and inhibitory activities against cancer cells. The phase III clinical trial is planned for the treatment of Hepatocellular carcinoma.

Ceralifimod (ONO-4641) is an oral, selective Sphingosine 1-phosphate receptor 1 and 5 agonist. It was studied in the phase 2 trials for the treatment of multiple sclerosis, however, further, development was discontinued.

DICHLORISONE is a synthetic corticosteroid used topically for its glucocorticoid activity in the treatment of various skin disorders.

LXR-623 is a is a highly selective and orally bioavailable synthetic agonist of Liver X receptors (LXR) alpha and beta that has shown promise in animal models of atherosclerosis. In nonhuman primates with normal lipid levels, LXR-623 significantly reduced total (50-55%) and LDL-cholesterol (LDLc) (70-77%) in a time- and dose-dependent manner and increased expression of the target genes ABCA1 and ABCG1 in peripheral blood cells of rats, mice and monkeys. LXR-623 demonstrated efficacy for reducing lesion progression in the murine LDLR(-/-) atherosclerosis model with no associated increase in hepatic lipogenesis either in this model or Syrian hamsters and displayed a unique and favorable pharmacological profile suggesting it may be suitable for evaluation in patients with atherosclerotic dyslipidemia. Results from a single ascending-dose study of the safety, pharmacokinetics, and pharmacodynamics of LXR-623 in healthy humans confirmed the effect of LXR-623 concentration on ABCA1 and ABCG1 expression. LXR-623 was absorbed rapidly with peak concentrations (Cmax) achieved at about 2 hours and increased Cmax and area under the concentration-time curve in a dose-proportional manner. The mean terminal disposition half-life was between 41 and 43 hours independently of dose. Central nervous system—related adverse events were observed at the 2 top doses tested. LXR-623 showed brain penetration and caused tumor regression in a glioblastoma (GBM) mouse model which characterize it as a potentially potent, highly-specific anti-GBM therapy.
