AZD-7687 is a potent inhibitor of Diacylglycerol O-acyltransferase 1 (DGAT1) which was developed by AstraZeneca for the treatment obesity and type 2 diabetes mellitus. AZD-7687 reached phase I of clinical trials, but was discontinued by unknown reasons.

AZD4017, a 11β-hydroxysteroid dehydrogenase type 1 inhibitor, has been developed by AstraZeneca for the treatment of obesity, raised intraocular pressure (IOP) and type 2 diabetes. Inhibition of 11β-HSD1 is an attractive mechanism for the treatment of obesity and other elements of the metabolic syndrome. However, studies were discontinued due to safety and efficacy reasons. Besides, specific inhibition of 11β-HSD1 can decrease intracranial pressure and consequently treat patients with Idiopathic Intracranial Hypertension (IIH), thus AZD4017 participated in phase II clinical trials to treat this disease. IIH, also known as benign intracranial hypertension or pseudotumor cerebri, is a condition of unknown etiology characterized by elevated intracranial pressure (ICP) and papilledema. In addition, AZD4017 in combination with prednisolone participated in phase II clinical trials for patients with Iatrogenic Cushing's Disease. It was postulated that the adverse metabolic effects of prednisolone could be reduced by co-administration of AZD4017.

Saroglitazar, a dual peroxisome proliferator-activated receptor PPAR-α/γ agonist, was an emerging therapeutic option on glycemic and lipid parameters. The Zydus Group has launched LipaglynTM ((Saroglitazar) in India for diabetic dyslipidemia and hypertriglyceridemia with type 2 diabetes mellitus not controlled by statin therapy. In addition, saroglitazar participated in phase II clinical trials that completed enrolment in patients with primary biliary cholangitis and in patients with non-alcoholic steatohepatitis.

RO-638695 (also known as Miridesap, CPHPC and GSK-2315698) is an antineoplastic and a serum amyloid P component inhibitor. RO-638695 almost completely depletes circulating serum amyloid P component (SAP), but a small amount of SAP is left for recognition by subsequently administered therapeutic IgG anti-SAP antibodies. SAP is a blood protein that is the target of a novel immunotherapy approach. RO-638695 has therefore been evaluated in phase I and II clinical trials for its safety and potential in treatment of diseases like Alzheimer’s disease, HIV infection and other diseases with systemic amyloid deposition.

Arena Pharmaceuticals was developing APD-597 (JNJ-38431055), a small molecule, an orally active agonist of the G-protein coupled receptor 119 (GPR119), for the treatment of Type 2 diabetes mellitus. JNJ-38431055 was selected for preclinical development based on a good balance between agonist potency, intrinsic activity and in particular on its good solubility and reduced drug-drug interaction potential. In addition, extensive in vivo studies showed a more favorable metabolic profile that may avoid the generation of long-lasting metabolites with the potential to accumulate in clinical studies. In humans, single-dose oral JNJ-38431055 increased postmeal plasma glucagon-like peptide 1 (GLP-1), glucose-dependent insulinotropic peptide (GIP), and peptide YY (PYY) concentrations but did not significantly decrease glucose excursion or increase insulin secretion. However, in a graded glucose infusion study, JNJ-38431055 was shown to induce a higher insulin secretion rate (ISR) relative to placebo at elevated plasma glucose levels. These studies provide evidence for the potential efficacy of JNJ-38431055 as an antidiabetes agent in humans.

Iodopyracet (Diodone) is a radiocontrast agent used in urography before 1950. Renal clearance of iodopyracet is characterized by supply-limited elimination at low plasma concentrations and capacity-limited elimination at high plasma levels. Iodopyracet to be an effective agent for the estimation of renal plasma flow and tubular function has been used extensively in physiological studies. In 1945 was found, that p-aminohippuric acid was in some ways superior to diodone for these estimations in man because the urine and plasma blanks are small and because diodone penetrates human red blood cells whereas p-aminohippuric acid does not.

Iodopyracet I-125 is radiolabeled Iodopyracet

Cobalt protoporphyrin (CoPP) is a potent HO-1 inducer and generally known to be an antioxidant in various cell types. CoPP has been shown to downregulate various cytochrome P450 isoforms, and various mechanisms of action have been attributed to its ability to induced HO- 1. It has also been used to promote endogenous carbon dioxide (CO) generation and protect against myocardial infarction in vivo. CoPP also participated in regulating the inflammatory response in CNS which mainly suppressed inflammatory component. It has been demonstrated that CoPP reduced LPS/Interleukin 13 (IL-13)-induced microglial death.
