Nucleocidin is a fluorine-containing nucleoside produced by Streptomyces calvus . [1]
Nucleocidin stems from the ribonucleoside adenosine [2] - is unique because it possess two rare functional groups: a fluorine atom and a sulfamyl ester [3]
During 1968 the attempts to identify nucleocidin were made and at that time it was assigned to a structure of a 9-adenyl-4' -sulfamoyloxypentofuranoside, which was mainly based on experiments from PMR and mass spectroscopy, as well as testing in chemical reactions. It was ultimately proven to have a structure of a 4' -fluoro-5' -O-sulphamoyladenosine. [4]
Nucleocidin is an antibiotic produced from Streptomyces calvus . Though toxic to mammals, it is able to function against bacteria both gram negative gram positive. It may be used against trypanosomes. [5]
Though commonly known to be produced by Streptomyces calvus, nucleocidin is produced in greater yield by Streptomyces virens and Streptomycesaurorectus. [6]
The compound is capable of interrupting the synthesis of peptides. [7]
Human embryonic kidney 293 cells, also often referred to as HEK 293, HEK-293, 293 cells, are an immortalised cell line derived from HEK cells isolated from a female fetus in the 1970s.
Daptomycin, sold under the brand name Cubicin among others, is a lipopeptide antibiotic used in the treatment of systemic and life-threatening infections caused by Gram-positive organisms.
Trifluoroacetic acid (TFA) is an organofluorine compound with the chemical formula CF3CO2H. It is a haloacetic acid, with all three of the acetyl group's hydrogen atoms replaced by fluorine atoms. It is a colorless liquid with a vinegar-like odor.
Organofluorine chemistry describes the chemistry of organofluorine compounds, organic compounds that contain a carbon–fluorine bond. Organofluorine compounds find diverse applications ranging from oil and water repellents to pharmaceuticals, refrigerants, and reagents in catalysis. In addition to these applications, some organofluorine compounds are pollutants because of their contributions to ozone depletion, global warming, bioaccumulation, and toxicity. The area of organofluorine chemistry often requires special techniques associated with the handling of fluorinating agents.
Lipstatin is a potent, irreversible inhibitor of pancreatic lipase. It is a natural product that was first isolated from the actinobacterium Streptomyces toxytricini.
In enzymology, a 2,5-dihydroxypyridine 5,6-dioxygenase (EC 1.13.11.9) is an enzyme that catalyzes the chemical reaction
In enzymology, a fluorothreonine transaldolase is an enzyme that catalyzes the chemical reaction
Uridine-cytidine kinase 2 (UCK2) is an enzyme that in humans is encoded by the UCK2 gene.
The gal operon is a prokaryotic operon, which encodes enzymes necessary for galactose metabolism. Repression of gene expression for this operon works via binding of repressor molecules to two operators. These repressors dimerize, creating a loop in the DNA. The loop as well as hindrance from the external operator prevent RNA polymerase from binding to the promoter, and thus prevent transcription. Additionally, since the metabolism of galactose in the cell is involved in both anabolic and catabolic pathways, a novel regulatory system using two promoters for differential repression has been identified and characterized within the context of the gal operon.
The fluorinase enzyme catalyzes the reaction between fluoride ion and the co-factor S-adenosyl-L-methionine to generate L-methionine and 5'-fluoro-5'-deoxyadenosine, the first committed product of the fluorometabolite biosynthesis pathway. The fluorinase was originally isolated from the soil bacterium Streptomyces cattleya, but homologues have since been identified in a number of other bacterial species, including Streptomyces sp. MA37, Nocardia brasiliensis and Actinoplanes sp. N902-109. This is the only known enzyme capable of catalysing the formation of a carbon-fluorine bond, the strongest single bond in organic chemistry.
Paxilline is a toxic, tremorgenic diterpene indole polycyclic alkaloid molecule produced by Penicillium paxilli which was first characterized in 1975. Paxilline is one of a class of tremorigenic mycotoxins, is a potassium channel blocker, and is potentially genotoxic.
Clavams are a class of antibiotics. This antibiotic is derived from Streptomyces clavuligerus NRRL 3585. Clavam is produced to form a new β-lactam antibiotic. This class is divided into the clavulanic acid class and the 5S clavams class. Both groups are the outcomes of the fermentation process produced by Streptomyces spp. Clavulanic acid is a broad-spectrum antibiotic and 5S clavams may have anti-fungal properties. They are similar to penams, but with an oxygen substituted for the sulfur. Thus, they are also known as oxapenams.
Keratinases are proteolytic enzymes that digest keratin.
C2C12 is an immortalized mouse myoblast cell line. The C2C12 cell line is a subclone of myoblasts that were originally obtained by Yaffe and Saxel at the Weizmann Institute of Science in Israel in 1977. Developed for in vitro studies of myoblasts isolated from the complex interactions of in vivo conditions, C2C12 cells are useful in biomedical research. These cells are capable of rapid proliferation under high serum conditions and differentiation into myotubes under low serum conditions. Mononucleated myoblasts can later fuse to form multinucleated myotubes under low serum conditions or starvation, leading to the precursors of contractile skeletal muscle cells in the process of myogenesis. C2C12 cells are used to study the differentiation of myoblasts, osteoblasts, and myogenesis, to express various target proteins, and to explore mechanistic biochemical pathways.
Fluorine may interact with biological systems in the form of fluorine-containing compounds. Though elemental fluorine (F2) is very rare in everyday life, fluorine-containing compounds such as fluorite occur naturally as minerals. Naturally occurring organofluorine compounds are extremely rare. Man-made fluoride compounds are common and are used in medicines, pesticides, and materials. Twenty percent of all commercialized pharmaceuticals contain fluorine, including Lipitor and Prozac. In many contexts, fluorine-containing compounds are harmless or even beneficial to living organisms; in others, they are toxic.
Streptomyces cacaoi is a bacterium species from the genus of Streptomyces. Streptomyces cacaoi produces polyoxine.
Streptomyces calvus is a bacterium species from the genus of Streptomyces which has been isolated from soil in Dinepur in India. Streptomyces calvus produces nucleocidin, adiposin 1 and adiposin 2.
Carbocyclic nucleosides are nucleoside analogues in which a methylene group has replaced the oxygen atom of the furanose ring. These analogues have the nucleobase attached at a simple alkyl carbon rather than being part of a hemiaminal ether linkage. As a result, they have increased chemical stability. They also have increased metabolic stability because they are unaffected by phosphorylases and hydrolases that cleave the glycosidic bond between the nucleobase and furanose ring of nucleosides. They retain many of the biological properties of the original nucleosides with respect to recognition by various enzymes and receptors.
Fluasterone, also known as 3β-dehydroxy-16α-fluoro-DHEA or 16α-fluoroandrost-5-en-17-one, is a fluorinated synthetic analogue of dehydroepiandrosterone (DHEA) which was under investigation by Aeson Therapeutics for a variety of therapeutic indications including cancer, cardiovascular diseases, diabetes, obesity, and traumatic brain injury among others but was ultimately never marketed. It is a modification of DHEA in which the C3β hydroxyl has been removed and a hydrogen atom has been substituted with a fluorine atom at the C16α position. Fluasterone reached phase II clinical trials prior to the discontinuation of its development.
Azvudine is an antiviral drug which acts as a reverse transcriptase inhibitor. It was discovered for the treatment of Hepatitis C and has since been investigated for use against other viral diseases such as AIDS and COVID-19, for which it was granted conditional approval in China.
