Loxiglumide is a potent, orally active, and selective CCK-A receptor antagonist which stimulates calorie intake and hunger feelings in humans. Loxiglumide inhibits pancreatic secretion of digestive enzymes, and also blocks CCK-induced gastric secretions and emptying. Intravenous administration of loxiglumide antagonized the CCK-induced reduction of gastric emptying in rats, acceleration of intestinal transport in mice, increase in ileal motility in rabbits, gallbladder contraction in guinea pigs and acceleration of gallbladder emptying in mice.

Patamostat (E-3123) is a protease inhibitor in vivo and in vitro. Inhibitory activity was shown toward trypsin, thrombin, plasmin, cathepsin-B and kallikrein. Patamostat is effective toward experimental pancreatitis and disseminated intravascular coagulation (animal models).

Cycloheximide is an antibiotic produced by fermentation culture of Streptomyces griseus, Streptomyces noursei, Streptomyces albulus, Streptomyces naraensis, or other cycloheximide-producing microorganism. It was first discovered by A. Whiffen et al. in 1946. She observed the activity of the compound against the yeasts and it became known as the first antifungal antibiotic. Cycloheximide has been marketed as a plant fungicide for many years and this use continues mainly against fungal diseases of turf and for powdery mildew on roses. More recently, cycloheximide has been recognized and is being developed as an abscission agent for citrus fruits and olives. Due to significant toxic side effects, including DNA damage, teratogenesis, and other reproductive effects, cycloheximide is generally used only in in vitro research applications, and is not suitable for human use as a therapeutic compound. Cycloheximide is an antimitotic and an inhibitor of the synthesis of both DNA and protein.

Biologically, methanogens in the colon can use carbon dioxide and hydrogen to produce methane as a by-product. It was previously considered that humans do not utilize methane. However, in a recent study on rodents, results demonstrated that methane could exert anti-inflammatory, anti-oxidant and anti-apoptotic effects. Furthermore, it has bee suggested, that methane-rich saline could be a promising therapeutic agent for clinical treatment of pancreatitis. Methane gas may also be a promising option for the clinical treatment of Acute Lung Injury and Spinal Cord Injury. The exact mechanism underlying the antioxidative, anti-inflammatory, and antiapoptotic activities of methane is not obvious. Different researchers have proposed different hypotheses. Some have hypothesized that methane might accumulate transiently at the interfaces of cell membranes, thereby changing the physicochemical properties or the in-situ functionality of proteins embedded within this environment. Other investigators have suggested that methane could exert effects on membrane channels affecting G-proteins, membrane or receptor-mediated signaling, or acetylcholine-activated ion channel kinetics. It is unknown if mammalian cells contain an oxygenase that is capable of using methane as a substrate, or if the biological effects of methane are caused by the formation of small amounts of the reactive alcohol, methanol, and/or changes in the redox milieu of the cell due to changes in NAD(P)+/NAD(P)H ratio, and whether or not there is a cellular “receptor” for methane. There are also questions remaining around the difference between intraperitoneal vs inhaled administration of methane.

CID-2858522 is the potent and selective inhibitor of protein kinase C (PKC)-induced activation of the NF-κB pathway (IC50 < 0.1 μM for PMA-stimulated IL-8 production). CID-2858522 inhibits antigen receptor-stimulated NF-κB activation in chronic lymphocytic leukemia (CLL) B cells. CID-2858522 does not inhibit other NF-κB pathways, including that activated by tumor necrosis factor (TNF).

Sodium tauroglycocholate presents in ENZAR FORTE tablet, together with enzymes: amylase, lipase and protease. ENZAR FORTE is indicated for the treatment of the following digestive symptoms: indigestion/dyspepsia; flatulence; bloating; fullness after eating; heartburn; anorexia; hepatic and pancreatic insufficiency; post-operative digestive upsets and convalescence. Discomfort, flatulence, and abdominal colic may result when the bodies own pancreatic enzymes cannot cope with excessive quantities of food consumed. In such cases, the enzymes present in ENZAR FORTE enhance the digestive processes in a natural way, thereby reducing the amount of undigested food available for fermentation & putrefaction. Amylase enzyme helps in the digestion of starch, lipase is involved in the digestion of lipids, and protease is required for digestion of proteins. The advantage of bile salt i.e. sodium tauroglycocholate for improving absorption of fat & fat-soluble vitamins.

Dexloxiglumide is a selective antagonist of cholecystokinin receptor A (CCKA, CCK1). It is the dextro isomeric form of loxiglumide, Dexloxiglumide was investigated for treatment of irritable bowel syndrome. Its development in USA was discontinued.

Gabexate is a synthetic protease inhibitor, was shown to be effective in treating patients with sepsis-associated disseminated intravascular coagulation in which tumor necrosis factor-alpha (TNF-alpha) plays a critical role. Gabexate mesylate is a drug marketed only in Italy and Japan and it is considered an essential drug in the treatment of acute pancreatitis. Gabexate is marketed under the brand name REMINARON among others in Japan. It relieves inflammatory symptoms in the pancreas by inhibiting various enzymes. It also improves organ disorders and bleeding tendency caused by blood clots in blood vessels by inhibiting blood coagulation. It is usually used to treat acute pancreatitis with deviation of proteolytic enzymes (such as trypsin, kallikrein and plasmin), acute exacerbation of chronic recurrent pancreatitis, acute pancreatitis after surgery and disseminated intravascular coagulation.

(R)-FK480 is enantiomer of a cholecystokin-type-A (CCK-A) receptor antagonist FK480. Binding of (R)-FK480 to CCK-A is 26 times less potent than (S)-FK480.

Nafamostat mesilate (NM), a synthetic serine protease inhibitor, has anticoagulant and anti-inflammatory properties. Nafamostat is approved and marketed in Japan. It relieves symptoms such as pain due to inflammation of the spleen. It improves visceral disorders and bleeding tendency caused by blood clotting tendency in the vessels. It prevents coagulation in the blood circuit during hemodialysis. It is usually used to improve acute symptoms of pancreatitis (acute pancreatitis, acute exacerbation phase of chronic pancreatitis, post-operative acute pancreatitis, acute pancreatitis after pancreatography, traumatic pancreatitis) and to prevent disseminated intravascular coagulation (DIC) and clotting of perfusing blood in extracorporeal blood circuit. Nafamostat mesilate significantly inhibits the release of platelet beta-thromboglobulin (beta TG) at 60 and 120 min. Nafamostat mesilate (NM) prevents any significant release of neutrophil elastase; at 120 min, plasma elastase-alpha 1-antitrypsin complex is 0.16 mg/mL in the NM group and 1.24 mg/mL in the control group. Nafamostat mesilate completely inhibits formation of complexes of C1 inhibitor with kallikrein and FXIIa.
