pyrimidine

Pyrimidine (Metadiazine)s are heterocyclic, six-membered, nitrogen-containing carbon ring structures, with uracil, cytosine and thymine being the basal structures of ribose-containing nucleosides (uridine, cytidine, and thymidine respectively), or deoxyribose-containing deoxynucleosides, and their corresponding ribonucleotides or deoxyribonucleotides. Pyrimidines serve essential functions in human metabolism as ribonucleotide bases in RNA (uracil and cytosine), and as deoxyribonucleotide bases in DNA (cytosine and thymine), and are linked by phosphodiester bridges to purine nucleotides in double-stranded DNA, in both the nucleus and the mitochondria. Pyrimidine activated sugars are also involved in polysaccharide and phospholipid synthesis, glucuronidation in detoxification processes, glycosylation of proteins and lipids and in the recently identified novel endothelium-derived vasoactive dinucleotides.

Pyrazolo[1,5-a]pyrimidine 4h is a morpholine derivative that is a selective antagonist of the adenosine A2A receptor. It has been shown to be neuroprotective in animal models of Parkinson's disease and Huntington's chorea.

Orotic acid (Vitamin B13) is an intermediate product in pyrimidine metabolism.

Orotic acid zinc (Zinc Orotate) salt dihydrate is an intermediate product in pyrimidine synthesis.

Ecamsule is a benzylidene camphor derivative, many of which are known for their excellent photostability. It can be added to many sunscreens to filter out UVA rays.

Sorivudine (BV-araU) has antiviral activity against several viruses including varicella zoster virus, herpes simplex type 1 virus, and Epstein-Barr virus by interfering with viral DNA synthesis.

Cardiogenol C is a cardiomyogenesis inducer in embryonic stem cells.

EGFR-IN-12 (EGFR Inhibitor) is a cell permeable and selective inhibitor of EGFR kinase (IC50: 21 nM) and blocks receptor autophosphorylation in cells.

Deoxycytidine triphosphate trisodium salt (2'-DEOXYCYTIDINE-5'-TRIPHOSPHATE TRISODI) contributes to antibiotic lethality in stationary-phase mycobacteria.

Deoxycytidine triphosphate is a nucleoside triphosphate.It is a raw material in DNA synthesis. Deoxycytidine triphosphate has many applications, such as real-time PCR, cDNA synthesis, and DNA sequencing.

Cardiogenol C hydrochloride (Cardiogenol C) can induces the differentiation of ESCs into cardiomyocytes (EC50= 100 nM).

STL127705 (Compound L) is a potent inhibitor of the Ku 70/80 heterodimer protein, disrupting Ku70/80-DNA interaction with an IC50 of 3.5 μM, and inhibiting Ku-dependent DNA-PKCS kinase activation with an IC50 of 2.5 μM.

SPOP-IN-6b is an effective inhibitor of speckle-type POZ protein (SPOP) with an IC50 of 3.58 μM and can be used in stuides about the treatment of renal cancer.

Orotic acid monohydrate is an intermediate product in pyrimidine metabolism.

Pyrazoloadenine (4-Aminopyrazolo[3,4-d]pyrimidine) is the inhibitor of human xanthine oxidase.

INCB032304 is an important pharmaceutical intermediate. It can be used in the preparation of Ruxolitinib phosphate (I008849), a janus kinase inhibitor, and in the preparation of Barretinib.

IRAK4 modulator-2 (Compound 5) is a selective dual inhibitor of IRAK4 and IRAK1, with IC₅₀ values of 0.005 μM and 0.97 μM respectively. It may be employed in research concerning autoimmune and inflammatory diseases such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease.

5,6-dihydro-5-Fluorouracil (5-FUH2) is an inactive metabolite of 5-FU and can be used for the study of organismal metabolism.

Syk inhibitor II, a cell-permeable, ATP-competitive, pyrimidine-carboxamide compound, selectively and reversibly inhibits Syk (IC50 = 41 nM).

Purine (7H-Imidazo(4,5-d)pyrimidine) is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Two of the bases in nucleic acids, adenine and guanine, are purines. Purines from food (or from tissue turnover) are metabolised by several enzymes, including xanthine oxidase, into uric acid. High levels of uric acid can predispose to gout when the acid crystalises in joints; this phenomenon only happens in humans and some animal species (e.g. dogs) that lack an intrinsic uricase enzyme that can further degrade uric acid.
