Fumagillin is a complex biomolecule and used as an antimicrobial agent. It was isolated in 1949 from the microbial organism Aspergillus fumigatus . [1]
It was originally used against microsporidian parasites Nosema apis infections in honey bees.[ citation needed ]
Some studies found it to be effective against some myxozoan parasites, including Myxobolus cerebralis, an important parasite of fish; however, in the more rigorous tests required for U.S. Food and Drug Administration approval, it was ineffective.[ citation needed ]
There are reports that fumagillin controls Nosema ceranae , [2] which has recently been hypothesized as a possible cause of colony collapse disorder. [3] [4] The latest report, however, has shown it to be ineffective against N. ceranae. [5] Fumagillin is also investigated as an inhibitor of malaria parasite growth. [6] [7]
Fumagillin has been used in the treatment of microsporidiosis. [8] [9] It is also an amebicide. [10]
Fumagillin can block blood vessel formation by binding to an enzyme methionine aminopeptidase 2 [11] and for this reason, the compound, together with semisynthetic derivatives, are investigated as an angiogenesis inhibitor [12] in the treatment of cancer.
The company Zafgen conducted clinical trials using the fumagillin analog beloranib for weight loss, [13] but they were unsuccessful. [14]
Fumagillin is toxic to erythrocytes in vitro at concentrations greater than 10 μM. [15]
Fumagillin and the related fumagillol (the hydrolysis product) have been a target in total synthesis, with several reported successful strategies, racemic, asymmetric, and formal. [16] [17] [18] [19] [20] [21] [22] [23] [24]
Nosema apis is a microsporidian, a small, unicellular parasite recently reclassified as a fungus that mainly affects honey bees. It causes nosemosis, also called nosema, which is the most common and widespread of adult honey bee diseases. The dormant stage of N. apis is a long-lived spore which is resistant to temperature extremes and dehydration, and cannot be killed by freezing the contaminated comb. Nosemosis is a listed disease with the Office International des Epizooties (OIE).
Microsporidiosis is an opportunistic intestinal infection that causes diarrhea and wasting in immunocompromised individuals. It results from different species of microsporidia, a group of microbial (unicellular) fungi.
Lisofylline (LSF) is a synthetic small molecule with novel anti-inflammatory properties. LSF can effectively prevent type 1 diabetes in preclinical models and improves the function and viability of isolated or transplanted pancreatic islets. It is a metabolite of pentoxifylline.
Antiparasitics are a class of medications which are indicated for the treatment of parasitic diseases, such as those caused by helminths, amoeba, ectoparasites, parasitic fungi, and protozoa, among others. Antiparasitics target the parasitic agents of the infections by destroying them or inhibiting their growth; they are usually effective against a limited number of parasites within a particular class. Antiparasitics are one of the antimicrobial drugs which include antibiotics that target bacteria, and antifungals that target fungi. They may be administered orally, intravenously or topically. Overuse or misuse of antiparasitics can lead to the development of antimicrobial resistance.
(+)-CPCA is a stimulant drug similar in structure to pethidine and to RTI-31, but nocaine is lacking the two-carbon bridge of RTI-31's tropane skeleton. This compound was first developed as a substitute agent for cocaine.
Nosema ceranae is a microsporidian, a small, unicellular parasite that mainly affects Apis cerana, the Asiatic honey bee. Along with Nosema apis, it causes the disease nosemosis, the most widespread of the diseases of adult honey bees. N. ceranae can remain dormant as a long-lived spore which is resistant to temperature extremes and dehydration. This fungus has been shown to act in a synergistic fashion with diverse insecticides such as fipronil or neonicotinoids, by increasing the toxicity of pesticides for bees, leading to higher bee mortality. It may thus play an indirect role in colony collapse disorder. In addition, the interaction between fipronil and N. ceranae induces changes in male physiology leading to sterility.
Troparil is a stimulant drug used in scientific research. Troparil is a phenyltropane-based dopamine reuptake inhibitor (DRI) that is derived from methylecgonidine. Troparil is a few times more potent than cocaine as a dopamine reuptake inhibitor, but is less potent as a serotonin reuptake inhibitor, and has a duration spanning a few times longer, since the phenyl ring is directly connected to the tropane ring through a non-hydrolyzable carbon-carbon bond. The lack of an ester linkage removes the local anesthetic action from the drug, so troparil is a pure stimulant. This change in activity also makes troparil slightly less cardiotoxic than cocaine. The most commonly used form of troparil is the tartrate salt, but the hydrochloride and naphthalenedisulfonate salts are also available, as well as the free base.
Methionine aminopeptidase 2 is an enzyme that in humans is encoded by the METAP2 gene.
The adenosine A2B receptor, also known as ADORA2B, is a G-protein coupled adenosine receptor, and also denotes the human adenosine A2b receptor gene which encodes it.
Metabotropic glutamate receptor 3 (mGluR3) is an inhibitory Gi/G0-coupled G-protein coupled receptor (GPCR) generally localized to presynaptic sites of neurons in classical circuits. However, in higher cortical circuits in primates, mGluR3 are localized post-synaptically, where they strengthen rather than weaken synaptic connectivity. In humans, mGluR3 is encoded by the GRM3 gene. Deficits in mGluR3 signaling have been linked to impaired cognition in humans, and to increased risk of schizophrenia, consistent with their expanding role in cortical evolution.
Tropoxane (O-1072) is an aryloxytropane derivative drug developed by Organix Inc., which acts as a stimulant and potent dopamine and serotonin reuptake inhibitor. It is an analogue of dichloropane where the amine nitrogen has been replaced by an oxygen ether link, demonstrating that the amine nitrogen is not required for DAT binding and reuptake inhibition.
In organic chemistry, diazirines are a class of organic molecules consisting of a carbon bound to two nitrogen atoms, which are double-bonded to each other, forming a cyclopropene-like ring, 3H-diazirine. They are isomeric with diazocarbon groups, and like them can serve as precursors for carbenes by loss of a molecule of dinitrogen. For example, irradiation of diazirines with ultraviolet light leads to carbene insertion into various C−H, N−H, and O−H bonds. Hence, diazirines have grown in popularity as small, photo-reactive, crosslinking reagents. They are often used in photoaffinity labeling studies to observe a variety of interactions, including ligand-receptor, ligand-enzyme, protein-protein, and protein-nucleic acid interactions.
Arylcyclohexylamines, also known as arylcyclohexamines or arylcyclohexanamines, are a chemical class of pharmaceutical, designer, and experimental drugs.
3,4-Dichloromethylphenidate is a stimulant drug related to methylphenidate. Dichloromethylphenidate is a potent psychostimulant that acts as both a dopamine reuptake inhibitor and norepinephrine reuptake inhibitor, meaning it effectively boosts the levels of the norepinephrine and dopamine neurotransmitters in the brain, by binding to, and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft.
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.
The cortistatins are a group of steroidal alkaloids first isolated in 2006 from the marine sponge Corticium simplex. The cortistatins were first discovered in a search for naturally occurring compounds that inhibit proliferation of human umbilical vein endothelial cells (HUVECs), with cortistatin A being the most potent compound in the class.
KM-233 is a synthetic cannabinoid drug which is a structural analog of Δ8-tetrahydrocannabinol (THC), the less active but more stable isomer of the active component of Cannabis. KM-233 differs from Δ8-THC by the pentyl side chain being replaced by a 1,1-dimethylbenzyl group. It has high binding affinity in vitro for both the CB1 and CB2 receptors, with a CB2 affinity of 0.91 nM and 13-fold selectivity over the CB1 receptor. In animal studies, it has been found to be a potential treatment for glioma, a form of brain tumor. Many related analogues are known where the 1,1-dimethylbenzyl group is substituted or replaced by other groups, with a fairly well established structure-activity relationship.
Cereblon E3 ligase modulators, also known as immunomodulatory imide drugs (IMiDs), are a class of immunomodulatory drugs containing an imide group. The IMiD class includes thalidomide and its analogues. These drugs may also be referred to as 'Cereblon modulators'. Cereblon (CRBN) is the protein targeted by this class of drugs.
4-Fluoromethylphenidate is a stimulant drug that acts as a higher potency dopamine reuptake inhibitor than the closely related methylphenidate.
Fumarranol is a drug which acts as an inhibitor of the type 2 methionine aminopeptidase enzyme METAP2. It was derived by structural modification of the natural product fumagillin. It was originally developed as an anti-angiogenesis drug for the treatment of cancer, but it was subsequently found to bind with high affinity to the METAP2 enzyme in malaria parasites and has been investigated as a potential treatment for malaria.
