Pyrimidin bildet farblose, charakteristisch riechende Kristalle, die schon oberhalb von 20-22 °C schmelzen. Oberhalb des Schmelzpunktes liegt eine farblose Flüssigkeit mit einem Normaldruck siedepunkt bei 124 °C vor. Die Verdampfungswärme beträgt 49,89 kJ·mol −1. Die Verbrennungsenthalpie wurde mit −2288,9 kJ·mol −1, die. Pyrimidine is one of two classes of heterocyclic nitrogenous bases found in the nucleic acids DNA and RNA: in DNA the pyrimidines are cytosine and thymine, in RNA uracil replaces thymine. Pyrimidine is the parent compound of the pyrimidines; a diazine having the two nitrogens at the 1- and 3-positions Pyrimidine Structure. Pyrimidine is a simple aromatic ring composed of two nitrogen atoms and four carbon atoms, with hydrogen atoms attached to each carbon. The carbon and nitrogen atoms are connected via alternating double and single bonds. This bond structure allows for resonance, or aromaticity, causing the ring to be very stable

Plant activators are chemicals that induce plant defense responses to various pathogens. Here, we reported a new potential plant activator, 6-(methoxymethyl)-2-[5-(trifluoromethyl)-2-pyridyl] pyrimidin-4-ol, named PPA2 (pyrimidin-type plant activator 2). Unlike the traditional commercial plant activator benzothiadiazole S-methyl ester (BTH), PPA2 was fully soluble in water, and it did not. A purine is a heterocyclic aromatic organic compound, consisting of a pyrimidine ring fused to an imidazole ring. Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. It is isomeric with two other forms of diazine The key difference between pyridine and pyrimidine is that pyridine structure resembles the structure of benzene with one methyl group replaced by a nitrogen atom, whereas pyrimidine structure, though it too resembles the structure of benzene, has two methyl groups replaced by nitrogen atoms.. Pyridine and pyrimidine are organic compounds. These are named as heterocyclic organic compounds. Vom Pyrimidin leiten sich die Basen Cytosin, Thymin und Uracil ab, wobei Thymin nur in der DNA, Uracil nur in der RNA vorkommt. Alle drei Basen können in jeweils zwei verschiedenen tautomeren Formen vorkommen. Die Hydroxylgruppe gibt ein Proton an ein Stickstoffatom im Ring ab.

Pyrimidine synthesi

Der ultraviolette Strahlungsanteil aus dem Sonnenlicht, besonders die energiereichen UV-B-Strahlen, schädigt die Erbsubstanz, indem er photochemische Reaktionen zwischen den Basen der DNA auslöst.Etwa 75% dieser Schäden können dem so genannten CPD-Typ (CPD= Cyclobutan-Pyrimidin-Dimere) zugerechnet werden Tymin är en av kvävebaserna som ingår i de nukleotider som bygger upp DNA. [1] Liksom cytosin och uracil är det en pyrimidin och består av en ring av kol- och kväve-atomer.I DNA binder sig tymin via två vätebindningar till den komplementerande basen adenin.I RNA finns den snarlika basen uracil istället för tymin.. I DNA förenas tymin med deoxiribos och bildar nukleosiden tymidin Spleen tyrosine kinase (Syk) tyrosine kinase plays essential roles in receptors for Fc portion of immunoglobulins and B cell receptor complex signaling in various inflammatory cells; therefore, inhibitors of Syk kinase may show potential as antiasthmatic/allergic therapeutics. We identified 2-[7-(3,4-dimethoxyphenyl)-imidazo[1,2- c ]pyrimidin-5-ylamino]-nicotinamide dihydrochloride (BAY 61. Orphanet: N [ (1R) 1 phenylethyl] 6 {1H pyrazolo [3,4 d]pyrimidin 4 yl}quinazolin 2 amine Die Pyrimidin-Synthese kann weiterhin mit verschiedenen Pyrimidin-Analoga blockiert werden. Ein Beispiel ist 5-Fluoruracil (5-FU). Aufgrund seiner Ähnlichkeit mit den Nukleinbasen Uracil, Cytosin und Thymin inhibiert 5-FU die Thymidylat-Synthase. Eingesetzt wird es als Chemotherapeutikum v.a. bei Darmkrebs und Brustkrebs, sowie äußerlich bei.
