Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis. It may be given by mouth or intravenously.
Membrane alanyl aminopeptidase also known as alanyl aminopeptidase (AAP) or aminopeptidase N (AP-N) is an enzyme that in humans is encoded by the ANPEP gene.
Artemether is a medication used for the treatment of malaria. The injectable form is specifically used for severe malaria rather than quinine. In adults, it may not be as effective as artesunate. It is given by injection in a muscle. It is also available by mouth in combination with lumefantrine, known as artemether/lumefantrine.
Fumagillin is a complex biomolecule and used as an antimicrobial agent. It was isolated in 1949 from the microbial organism Aspergillus fumigatus.
An angiogenesis inhibitor is a substance that inhibits the growth of new blood vessels (angiogenesis). Some angiogenesis inhibitors are endogenous and a normal part of the body's control and others are obtained exogenously through pharmaceutical drugs or diet.
Fosmidomycin is an antibiotic that was originally isolated from culture broths of bacteria of the genus Streptomyces. It specifically inhibits DXP reductoisomerase, a key enzyme in the non-mevalonate pathway of isoprenoid biosynthesis. It is a structural analogue of 2-C-methyl-D-erythrose 4-phosphate. It inhibits the E. coli enzyme with a KI value of 38 nM (4), MTB at 80 nM, and the Francisella enzyme at 99 nM. Several mutations in the E. coli DXP reductoisomerase were found to confer resistance to fosmidomycin.
Leucyl aminopeptidases are enzymes that preferentially catalyze the hydrolysis of leucine residues at the N-terminus of peptides and proteins. Other N-terminal residues can also be cleaved, however. LAPs have been found across superkingdoms. Identified LAPs include human LAP, bovine lens LAP, porcine LAP, Escherichia coli LAP, and the solanaceous-specific acidic LAP (LAP-A) in tomato.
Nitroxoline is an antibiotic that has been in use in Europe for about fifty years, and has proven to be very effective at combating biofilm infections. Nitroxoline was shown to cause a decrease in the biofilm density of P. aeruginosa infections, which would allow access to the infection by the immune system in vivo. It was shown that nitroxoline functions by chelating Fe2+ and Zn2+ ions from the biofilm matrix; when Fe2+ and Zn2+ were reintroduced into the system, biofilm formation was reconstituted. The activity of biofilm degradation is comparable to EDTA, but has a history of human use in clinical settings and therefore has a precedent with which to allow its use against “slimy” biofilm infections.
Matrix metallopeptidase 9 (MMP-9), also known as 92 kDa type IV collagenase, 92 kDa gelatinase or gelatinase B (GELB), is a matrixin, a class of enzymes that belong to the zinc-metalloproteinases family involved in the degradation of the extracellular matrix. In humans the MMP9 gene encodes for a signal peptide, a propeptide, a catalytic domain with inserted three repeats of fibronectin type II domain followed by a C-terminal hemopexin-like domain.
Methionine aminopeptidase 2 is an enzyme that in humans is encoded by the METAP2 gene.
Puromycin-sensitive amino peptidase also known as cytosol alanyl aminopeptidase or alanine aminopeptidase (AAP) is an enzyme that in humans is encoded by the NPEPPS gene. It is used as a biomarker to detect damage to the kidneys, and that may be used to help diagnose certain kidney disorders. It is found at high levels in the urine when there are kidney problems.
Methionine aminopeptidase 1 is an enzyme that in humans is encoded by the METAP1 gene.
Haemozoin is a disposal product formed from the digestion of blood by some blood-feeding parasites. These hematophagous organisms such as malaria parasites, Rhodnius and Schistosoma digest haemoglobin and release high quantities of free heme, which is the non-protein component of haemoglobin. Heme is a prosthetic group consisting of an iron atom contained in the center of a heterocyclic porphyrin ring. Free heme is toxic to cells, so the parasites convert it into an insoluble crystalline form called hemozoin. In malaria parasites, hemozoin is often called malaria pigment.
Beloranib is a former drug candidate for the treatment of obesity. It was discovered by CKD Pharmaceuticals and its clinical development was led by Zafgen. Drug development was halted in 2016 after deaths during clinical trials.
Cucurbitacin E is a biochemical compound from the family of cucurbitacins. These are found in plants which are member of the family Cucurbitaceae, most of them coming from traditional Chinese medicinal plants, but also in other plants such as pumpkins and gourds.
Methionyl aminopeptidase is an enzyme. This enzyme catalyses the following chemical reaction
The 3C-like protease (3CLpro) or main protease (Mpro), formally known as C30 endopeptidase or 3-chymotrypsin-like protease, is the main protease found in coronaviruses. It cleaves the coronavirus polyprotein at eleven conserved sites. It is a cysteine protease and a member of the PA clan of proteases. It has a cysteine-histidine catalytic dyad at its active site and cleaves a Gln–(Ser/Ala/Gly) peptide bond.
Amastatin, also known as 3-amino-2-hydroxy-5-methylhexanoyl-L-valyl-L-valyl-L-aspartic acid, is a naturally occurring, competitive and reversible aminopeptidase inhibitor that was isolated from Streptomyces sp. ME 98-M3. It specifically inhibits leucyl aminopeptidase, alanyl aminopeptidase, bacterial leucyl aminopeptidase, leucyl/cystinyl aminopeptidase (oxytocinase/vasopressinase), and, to a lesser extent, glutamyl aminopeptidase, as well as other aminopeptidases. It does not inhibit arginyl aminopeptidase. Amastatin has been found to potentiate the central nervous system effects of oxytocin and vasopressin in vivo. It also inhibits the degradation of met-enkephalin, dynorphin A, and other endogenous peptides.
Borrelidin is an 18-membered polyketide macrolide derived from several Streptomyces species. First discovered in 1949 from Streptomyces rochei, Borrelidin shows antibacterial activity by acting as an inhibitor of threonyl-tRNA synthetase and features a nitrile moiety, a unique functionality in natural products., Borrelidin also exhibits potent angiogenesis inhibition, which was shown in a rat aorta matrix model. Other studies have been performed to show that low concentrations of borrelidin can suppress growth and induce apoptosis in malignant acute lymphoblastic leukemia cells. Borredlidin's antimalarial activity has also been shown in vitro and in vivo.
TNP-470 is an methionine aminopeptidase 2 inhibitor. Although it was one of the first angiogenesis inhibitor tested in clinical trials, its potential was hampered by neurotoxic effects and lack of effectiveness.
