The invention discloses a pyrimidine derivative as the formula (I), wherein, the formula (I) is shown as the right, the pyrimidine derivative can be used for preparing medicines for treating related diseases of angiogenesis, particularly used for preparing medicines for treating tumors or … A ZnCl 2-catalyzed three-component coupling reaction allows the synthesis of various 4,5-disubstituted pyrimidine derivatives in a single step from functionalized enamines, triethyl orthoformate, and ammonium acetate. Organic & Medicinal Chem IJ. Use of 5-chloro-2,4,6-trifluoropyrimidine as a core scaffold for the synthesis of functionalised pyrimidine systems is assessed in reactions with a small range of nitrogen centred nucleophiles. Two pyrimidines, cytosine and thymine, are the DNA bases which, with two PURINES, form the genetic code. It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish-like smell.Pyridine is colorless, but older or impure samples can appear yellow. Xing Chen.

In the past few years, the therapeutic interest of pyrimidine derivatives in pharmaceutical and medicinal field has been given a Chemotherapy resistance is a major barrier to the treatment of triple-negative breast cancer (TNBC), and strategies to circumvent resistance are required. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. : 250 The other diazines are pyrazine (nitrogen atoms at the 1 and 4 positions) and pyridazine (nitrogen atoms at the 1 and 2 positions). Pyrimidine-condensed derivatives as the pharmacophore exhibit broad spectrum of biological activities encompassing antitubercular, antibacterial, antifungal, antiviral, anti-inflammatory, antimalarial, anticancer and anti-HIV. ChEBI. N. V. Lazarev, In: Proceedings of a Conference on the Use of Pyrimidine Derivatives in Oncology and Other Branches of Medicine [in Russian], Leningrad (1963). Laboratory for Innate Immune Systems, Center for Integrative Medical Sciences, RIKEN, 1-7-22 Suehiro, Tsurumi, Yokohama, Kanagawa 230-0045, Japan. Using in vitro and in vivo metabolic profiling of TNBC cells, we show that an increase in the abundance of pyrimidine nucleotides occurs in response to chemotherapy exposure. Recent Development of Pyrimidine-Containing Antimicrobial Agents Jianxing Zhuang[a] and Shutao Ma*[a] Multidrug-resistant bacterial infections have become an impor-tant cause of clinical death in the twenty-first century. One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has the nitrogen atoms at positions 1 and 3 in the ring. More by Yang Wang, Xing Chen. Using suitable functionalized starting materials, a set of NCEs were synthesized to demonstrate the application of the developed synthetic scheme. Unlike the low solubility of uric acid formed by catabolism of purines, the end products of pyrimidine catabolism (carbon dioxide, ammonia, β-alanine, and γ-aminoisobutyrate) are highly water soluble. 5 Related Records Expand this section. Much effort has been made to overcome this challenge. Fluorouracil (5FU), which inhibits thymidylate synthase; Floxuridine (FUDR) 6-azauracil (6-AU) Nucleoside analogues.
