Carumonam is a monobactam antibacterial agent. It was highly active in vitro against members of the family Enterobacteriaceae, Pseudomonas aeruginosa, and Haemophilus influenzae and weakly active against Streptococcus pneumoniae, but it was not active against Staphylococcus aureus. The excellent activity of carumonam against Gram-negative bacteria is related to its high affinity for their penicillin-binding proteins. It is indicated for the treatment of urinary tract infections, chronic respiratory infections, biliary tract infections, peritonitis, sepsis. Another factor that contributes to the excellent activity of carumonam against Gram-negative bacteria is its resistance to beta-lactamases. Adverse effects of the carumonam were limited to phlebitis at the intravenous infusion site; bloody diarrhea.

Stibogluconic acid (Sodium stibogluconate) is the pentavalent antimonial compound used to treat leishmaniasis and is only available for administration by injection. Sodium stibogluconate is sold in the UK as Pentostam (manufactured by GlaxoSmithKline). Sodium stibogluconate was granted orphan drug designation for the treatment of cutaneous leishmaniasis by the US FDA in January 2007. It is available in the United States only through the Centers for Disease Control. Sodium stibogluconate is indicated for the treatment of various types of a protozoal infection called leishmaniasis, which may result from sandfly bites in tropical and temperate parts of the world. It is also investigated for use/treatment in cancer. The mode of action of sodium stibogluconate is not clearly understood. In vitro exposure of amastigotes to 500 mg pentavalent antimony/ml results in a greater than 50% decrease in parasite DNA, RNA protein and purine nucleoside triphosphate levels. It has been postulated that the reduction in ATP (adenosine triphosphate) and GTP (guanosine triphosphate) synthesis contributes to decreased macromolecular synthesis. Sodium stibogluconate was shown to specifically inhibit type I DNA topoisomerase from Leishmania donovani through the inhibition of the unwinding and cleavage of the supercoiled plasmid pBR322, and to stabilize topoisomerase and DNA covalent complexes but not calf-thymus topoisomerase I and Escherichia coli DNA gyrase. Sodium stibogluconate is also a potent inhibitor of PTPases Src homology PTPase1 (SHP-1), SHP-2, and PTP1B but not the dual-specificity phosphatase mitogen-activated protein kinase phosphatase 1. Sodium stibogluconate combined with IFN-alpha-2b (IFN-α) inhibited solid tumor cell line growth in vitro, in vivo it was well tolerated and augmented cellular immune parameters.

Sulbenicillin (INN) is a penicillin antibiotic, product name: KEDACILLIN (SODIUM SULBENICILLIN) is effective against gram-negative bacteria, including Pseudomonas aeruginosa and anaerobic Bacteroides, and is also effective against gram-positive bacteria sensitive to Penicillin – G. It’s excreted into the urine and bile in high concentration. Therefore, urinary levels, well above those required to eradicate urinary pathogens, are achieved. It is indicated to treat urinary tract infections: pyelonephritis, pyelitis, pyonephrosis, cystitis and urethritis. Bile-duct infections: cholecystitis and cholangitis. Respiratory tract infections: acute and chronic bronchitis, bronchiectasis, bronchopneumonia, pneumonia and pulmonary suppuration. Obstetrics and Gynecology: intrauterine infection, adnexitis, intrapelvic infection and Bartholinitis. Superfacial suppurative diseases: folliculitis, furuncle, carbuncle, abscess, panaris, phlegmon, tonsilitis, peritonsilitis, peritonsillar abscess, erysipelas, ophthalmia, blepharitis, corneal ulcer, dacryocystitis, stye, post-operative wound infection and traumatic and burn infections. Peritonitis. Septicemia and sub-acute bacterial endocarditis. Sulbenicillin caused elongation of the bacterial cells. At the early stage of elongation, no demonstrable changes of ultrastructure of the cell wall were observed. At the late stage, lysis of the peptidoglycan layer occurred and spheroplast was formed. However, most of the outer membrane of the cell wall remained intact. Sulbenicillin acts upon the peptidoglycan layer, but not on the outer membrane.

Norfenefrine or meta-octopamine, also known as 3,β-dihydroxyphenethylamine, is an adrenergic agent used as a sympathomimetic drug which is marketed in Europe, Japan, and Mexico. Along with its structural isomer p-octopamine and the tyramines, norfenefrine is a naturally occurring, endogenous trace amine and plays a role as a minor neurotransmitter in the brain. Norfenefrine controls blood pressure in acute hypotensive states eg pheochromocytomectomy, sympathectomy, poliomyelitis, spinal anesth, MI, septicemia, blood transfusion and drug reactions. Adjunct in treatment of cardiac arrest and hypotension.

Cinepazet is an ethyl ester of cinepazic acid. It acts by inhibiting the influx of extracellular calcium into cells through the slow calcium channel in the cell membrane. In the 1970s cinepazet was marketed in France and Italy under tradename Vascoril for the treatment of angina.

Iobenguane, mainly use as a radiopharmaceutical, used in a scintigraphy method called MIBG scan. Synthetic guanethidine derivative that locates phaeochromocytomas and neuroblastomas. The radioisotope used can either be iodine-123 for imaging or iodine-131 for destruction of tissues that metabolize noradrenaline. Iodine 123 is a cyclotron-produced radionuclide that decays to Te 123 by electron capture. Images are produced by a I123 MIBG scintigraphy. It localizes to adrenergic tissue and thus can be used to identify the location of tumors such as pheochromocytomas and neuroblastomas. With I-131 it can also be used to eradicate tumor cells that take up and metabolize norepinephrine. The radioactive iodine component is responsible for its imaging properties. Iobenguane and guanethidine are substrates for the norepinephrine transporter (NET) and accumulate by the uptake mechanism into presynaptic nerve endings. Unlike norepinephrine, these drugs are protonated under physiologic conditions; therefore, they do not cross the blood–brain barrier and in vivo uptake is limited primarily to systemic neuronal tissue. The accumulation of iobenguane in myocardial tissue is also dictated by the high fraction of aortic blood flow that enters the coronary arteries. This physiology constitutes an ideal molecular targeting mechanism for diagnosis of various cardiac diseases, including heart failure, heart transplant rejection, ischemic heart disease, dysautonomia, and drug-induced cardiotoxicity, as well as cardiac neuropathy related to diabetes mellitus and Parkinson disease

Bendazac, (1-benzyl-1H-indazol-3-yl-oxy)-acetic acid, is structurally related to indomethacin. Its lysine salt has been reported to be absorbed better than the parent compound. It is applied topically as bendazac lysine 0.5% (wt/vol) aqueous solution for delaying the progression of cataract. Topical application of bendazac is associated with transient burning sensation. It reduces the secretion of the skin ulcer surface, promotes skin formation and accelerates tissue repair.

Trimazosin was originated by Pfizer and was licensed to Bristol-Myers Squibb worldwide except for Canada, Mexico and the USA. Trimazosin is a quinazoline antihypertensive agent structurally related to the selective alpha 1-adrenoceptor blocker prazosin. Trimazosin is an alpha adrenergic receptor antagonist. Compared with prazosin, trimazosin was a less potent but more efficacious hypotensive agent. At doses which caused equal or even greater hypotensive effects than those caused by prazosin, trimazosin caused less inhibition of pressor responses to phenylephrine. When administered during a maximum hypotensive response to prazosin, trimazosin caused an additional fall in pressure. Trimazosin is an effective antihypertensive when given by itself or in combination with a diuretic. Its ability to induce vasodilation without concomitant sodium retention or stimulation of the renin axis may be an important factor in its effectiveness. Trimazosin has the potential to cause sustained improvement in left ventricular function, both at rest and during exercise, in patients with chronic congestive heart failure (CHF).

Mebeverine is an antispasmodic with a direct action on the smooth muscle of the gastrointestinal tract. The exact mechanism of action is not known, but multiple mechanisms, such as a decrease in ion channel permeabilities, blockade of noradrenaline reuptake, a local anesthetic effects, as well as weak anti-muscarinic and phosphodiesterase inhibitory effect might contribute to the local effects of Mebeverine. This medicine is used to treat symptoms of irritable bowel syndrome (IBS) and similar problems such as chronic irritable colon, spastic constipation, mucous colitis and spastic colitis. Most people will not have problems with Mebeverine, but some may get some side effects, such as: difficulty in breathing, swelling of face, neck, tongue or throat, skin rash, red itchy skin.

Alrestatin, an inhibitor of aldose reductase, was studied in clinical trials for the treatment of diabetes. But this study was discontinued, because of the high hepatotoxicity events.
