Alfaprostol is a synthetic analogue of prostaglandin F2α. Its activity is similar to that of the endogenous PFG2α, causing luteolysis. Alfaprostol is recommended for use in the cow, sow and mare.

Oxantel is a narrow-spectrum anthelmintic effective against whipworms in dogs and cats. It is ineffective against other roundworms, flukes, tapeworms or external parasites. Oxantel acts on the nervous system of the worms as inhibitors of acetylcholinesterase. Oxantel, a cholinergic anthelmintic and fumarate reductase inhibitor, significantly inhibited biofilm formation by P. gingivalis and disrupted established biofilms at concentrations below its MIC against planktonic cells. Oxantel was more effective against P. gingivalis in biofilm than metronidazole, a commonly used antibiotic for periodontitis. When oxantel was administrated to human beings for the treatment of trichuriasis, no drug reaction or side effects were reported, and the results of hematologic, biochemical and urinary examinations didn’t reveal any significant drug-related changes.

Acipimox (5-methylpyrazinecarboxylic acid 4-oxide) is a new lipolysis inhibitor that has a distant chemical relationship with nicotinic acid (NA). The anti-lipolytic action of acipimox is mediated through suppression of intracellular cyclic AMP levels, with the subsequent decrease in cyclic AMP-dependent protein kinase activity, leading to the reduced association of hormone-sensitive lipase with triacylglycerol substrate in the lipid droplet of adipocytes. Acipimox has been identified as an agonist at G-protein coupled nicotinic acid HM74A and HM74B receptors. Acipimox (Olbetam) is indicated for the treatment as alternative or adjunct treatment to reduce triglyceride levels in patients who have not responded adequately to other treatments such as statin or fibrate treatment for hypertriglyceridaemia (Fredrickson type IV hyperlipoproteinaemia) and hypercholesterolaemia and hypertriglyceridaemia (Fredrickson type IIb hyperlipoproteinaemia).

Boldenone (INN, BAN), also known as Δ1-testosterone, 1-dihydrotestosterone, or androsta-1,4-dien-3-one-17β-ol (train name Equipoise) is a long-acting injectable anabolic agent for horses, supplied in a vial providing 50 mg boldenone undecylenate per mL in sesame oil with 3% (w/v) benzyl alcohol as a preservative. The activity of boldenone is mainly anabolic, with a low androgenic potency. Boldenone will increase nitrogen retention, protein synthesis increases appetite and stimulates the release of erythropoietin in the kidneys. Boldenone was synthesized in an attempt to create a long-acting injectable methandrostenolone (Dianabol), for androgen deficiency disorders. Boldenone acts similar to methandrostenolone with fewer adverse androgenic effects. Although commonly compared to nandrolone, boldenone lacks progesterone receptor interaction and all the associated progestogenic side effects. Equipoise (Boldenone Undecylenate Injection) is recommended as an aid for treating debilitated horses when an improvement in weight, haircoat or general physical condition is desired. Debilitation often follows disease or may occur following overwork and overexertion. Boldenone improves the general state of debilitated horses, thus aiding in correcting weight losses and improving appetite. It is not a substitute for a well-balanced diet. Optimal results can be expected only when good management and feeding practices are utilized. Boldenone should be considered only as adjunctive therapy to other specific and supportive therapy for diseases, surgical cases, and traumatic injuries.

Prednimustine is chlorambucil ester of prednisolone. Prednimustine is a cytostatic agent. Prednimustine is active against a wide variety of experimental tumors both in vivo and in vitro. In many of these tumor systems, prednimustine exhibits distinct advantages over a mixture of its constituents, chlorambucil and prednisolone. In vitro, a higher cell kill is obtained, and in vivo, at doses that are equally effective, prednimustine is less toxic. It has been used in the treatment of various malignancies, including chronic lymphatic leukaemia and non-Hodgkin's lymphomas. It has also been tested for use in the treatment of breast cancer

Carbomycin is a complex mixture containing carbomycin A with a small portion of carbomycin B. Carbomycin is produced by Streptomyces halstedii and acts as an antibiotic. The drug was approved by FDA under the name Magna-terramycin (in combination with oxytetracycline) for the treatment of bacterial chronic respiratory diseases in chickens. Carbomycin exerts its antibacterial action by binding within the large ribosomal subunit and thus inhibiting the protein synthesis in bacterias.

Sulfomyxin is an antibacterial sulfonamide. It is intended for use in chickens and turkeys as an aid in the treatment of disease caused or complicated by E. coli, such as colibacillosis and complicated chronic respiratory disease.

Nirogacestat (PF-3084014) is a tetralin imidazole gamma-secretase inhibitor. Gamma-secretase, a proteolytic enzyme complex, mediates processing of several integral membrane proteins including amyloid precursor protein and Notch. This compound can inhibit both Notch-related pathway in neoplasia and reduces amyloid-β production. Nirogacestat (PF-3084014) is under development by Pfizer for the treatment of cancer.

Maralixibat (Livmarli™) is a potent, apical, sodium‐dependent, bile acid transporter competitive inhibitor with minimal systemic absorption being developed by Mirum Pharmaceuticals for the treatment of rare cholestatic liver diseases including Alagille syndrome (ALGS), progressive familial intrahepatic cholestasis (PFIC) and biliary atresia. Maralixibat received its first approval on 29 September 2021, in the USA, for use in the treatment of cholestatic pruritus in patients with ALGS 1 year of age and older. Maralixibat is also under regulatory review for ALGS in Europe, and clinical development for cholestatic liver disorders including ALGS in patients under 1 year of age, PFIC and biliary atresia is continuing in several other countries. This article summarises the milestones in the development of maralixibat leading to this first approval for ALGS.

Lorlatinib is an investigational medicine that inhibits the anaplastic lymphoma kinase (ALK) and ROS1 proto-oncogene. Lorlatinib was specifically designed to inhibit tumor mutations that drive resistance to other ALK inhibitors. Lorlatinib has in vitro activity against ALK and number of other tyrosine kinase receptor related targets including ROS1, TYK1, FER, FPS, TRKA, TRKB, TRKC, FAK, FAK2, and ACK. Lorlatinib demonstrated in vitro activity against multiple mutant forms of the ALK enzyme, including some mutations detected in tumors at the time of disease progression on crizotinib and other ALK inhibitors. Moreover, lorlatinib possesses the capability to cross the blood-brain barrier, allowing it to reach and treat progressive or worsening brain metastases as well. Lorlatinib is a third-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor (TKI) indicated for the treatment of patients with ALK-positive metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on a) the prior use of crizotinib and at least one other ALK inhibitor for metastatic disease, or b) the prior use of alectinib as the first ALK inhibitor therapy for metastatic disease, or c) the prior use of certinib as the first ALK inhibitor therapy for metastatic disease.
