Halofenate (MK-185) was invented as a hypolipidemic and hypouricemic agent. It was shown that halofenate lower serum triglycerides and uric acid in patients with a variety of hyperlipidemias. Treatment of dyslipidemic type 2 diabetic patients also showed triglyceride lowering and, surprisingly, significant reductions in plasma glucose and insulin. Halofenate is a selective PPAR-γ modulator (SPPARγM). SPPARγMs are believed to bind in distinct manners to the ligand-binding pocket of PPAR-γ, leading to altered receptor conformational stability and resulting in distinct patterns of gene expression. Thus, was suggested that halofenate hold promising therapeutic potential in the treatment of type 2 diabetes, without the side effects. However, information about the current use of this compound is not available.

FLUFENISAL is a compound related to aspirin structurally, chemically, and pharmacologically. It was in clinical development as an analgesic and anti-inflammatory agent. However, its development was discontinued due to lack of sufficient superiority over aspirin.

Phorbol 12-myristate 13-acetate (PMA) also commonly known as 12-O-Tetradecanoylphorbol-13-acetate (TPA) is a phorbol ester that is commonly used to activate phospholipid-dependent protein kinase (protein kinase C). PMA/ TPA possesses potential antineoplastic effects and was studied in phase II clinical trials together with dexamethasone in patients with relapsed or refractory acute myeloid leukemia. In addition, PMA/ TPA participated in phase I trial for treating patients with hematologic cancer or bone marrow disorder that has not responded to previous treatment. Nevertheless, both clinical trials were terminated. Besides, PMA/ TPA was studied in patients with solid tumors, which had depressed white blood cell and neutrophil counts because of prior treatment with cytotoxic cancer chemotherapeutic drugs. It was shown, that the drug increased the low white blood cell and neutrophil counts toward the normal range.

Phenylacetate is the ester of a phenol and acetic acid. It is a metabolite of anticancer drug phenylbutyrate (PB), natural neurotransmitter phenylethylamine. Naturally, it is an odorant found in strawberries, passion fruit, and black tea. Phenylacetate level in urine was used as a marker for the diagnosis of some forms of unipolar major depressive disorders. Phenylacetate is used as a tool substrate to study esterase activity in the blood of patients in clinical studies of the effect of nutritional supplements on paraoxonase-1 levels.

Acetic anhydride is an esterification agent for use in prepn. of modified food starch and for acetylation of monoglycerides. Acetic anhydride is a versatile reagent for acetylations, the introduction of acetyl groups to organic substrates. Acetic anhydride is the chemical compound with the formula (CH3CO)2O (commonly abbreviated Ac2O). Ac2O is mainly used for acetylations leading to commercially significant materials. Its largest application is for the conversion of cellulose to cellulose acetate, which is a component of photographic film and other coated materials. Similarly it is used in the production of aspirin, acetyl salicylic acid, which is prepared by the acetylation of salicylic acid. It is also used as a wood preservative via autoclave impregnation to make a longer lasting timber. Ac2O is also used in many industrial processes for the production of plastics, textiles, dyes, photochemical agents, perfumes, explosives and cigarette filters. Because of its use for the synthesis of heroin by the diacetylation of morphine, acetic anhydride (known as 'AA' in clandestine chemistry circles) is listed as a U.S. DEA List II Precursor, and restricted in many other countries.
