  Rational Design of 5‘-Thiourea-Substituted α-Thymidine Analogues as Thymidine Monophosphate Kinase Inhibitors Capable of Inhibiting Mycobacterial Growth

  摘要：

  Recently, thymidine monophosphate kinase (TMPK) emerged as an attractive target for developing inhibitors of Mycobacterium tuberculosis growth. The elucidation of the X-ray structure of TMPK of M. tuberculosis (TMPKmt), as well as the structure of an earlier serendipitously discovered dimeric thymidine inhibitor, laid the foundation for the design of potent and selective TMPKmt inhibitors reported here. Several hits identified within a series of 3'-C-branched thiourea-substituted P-thymidine derivatives inspired us to construct a set of 5'-thiourea-substituted a-thymidine derivatives characterized by a similar relative orientation of the thymine and arylthiourea moieties. (x-Thymidine derivative 15, featuring a (3-trifluoromethyl-4-chlorophenyl)thiourea moiety, has a K-i of 0.6 mu M and a selectivity index of 600 versus human TMPK. Moreover, it represents the first TMPK inhibitor showing good inhibitory activity on growing M. bovis (MIC99 = 20 mu g/mL) and M. tuberculosis (MIC50 = 6.25 mu g/mL) strains.

  α-胸苷类似物作为新型抗疟药的合成与评价

  摘要：

  恶性疟原虫胸苷酸激酶 ( Pf TMPK) 是嘧啶核苷酸生物合成的关键酶。3-Trifluoromethyl-4-chloro-phenyl-urea-α-thymidine 已被报道为结核分枝杆菌TMPK ( Mt TMPK)的抑制剂。从这一点出发，我们设计、合成并评估了许多作为抗疟药的胸苷类似物。5'-尿素-α-和β-胸苷衍生物都是Pf TMPK 的中度抑制剂，并且还显示出对寄生虫生长的中度抑制。几种酶-抑制剂复合物的结构为改进抑制剂设计提供了基础。然而，我们发现某些 5'-尿素-α-胸苷类似物具有抗疟活性，其中PfTMPK 不是主要的作用方式。该系列的优化产生了具有有效抗疟活性的化合物（EC 50 = 28 nM；CC 50 = 29 μM）。

  Deoxythymidine derivatives according to formula (I) are disclosed. wherein: X may be O or S; and R1, R2, R3, R4 and R5 may each be independently selected from H, halo, C1-C6 alkyl, C1-C6 haloalkyl, nitro, phenyl, heteroaryl, substituted heteroaryl wherein the substituents may be C1-C6 alkyl or C1-C6 haloalkyl, benzyl, -CH2OAr, -OR6 and six-membered ring heterocyclic groups containing 1 or more O and/or N heteroatoms wherein any N heteroatom may be C1-C6 alkyl-substituted; and R6 may be selected from C1-C6 alkyl, phenyl, six-membered ring heterocyclic groups containing at least one O heteroatom, benzyl and substituted benzyl wherein the substituents may be halo, C1-C6 alkyl or C1-C6 alkoxy; R7 may be H or C1-C6 alkyl; and the stereochemistry of the bond depicted as 〰 is either α or β. Such derivatives have shown good inhibitory activity against malaria-causing parasites, e.g. Plasmodium falciparum, but have shown low levels of toxicity to human cells.

  Plasmodium falciparum thymidylate kinase (PfTMK) is a critical enzyme in the de novo biosynthesis pathway of pyrimidine nucleotides. N-(5′-Deoxy-α-thymidin-5′-yl)-N′-[4-(2-chlorobenzyloxy)phenyl]urea was developed as an inhibitor of PfTMK and has been reported as an effective inhibitor of P. falciparum growth with an EC50 of 28 nM [Cui, H., et al. (2012) J. Med. Chem. 55, 10948–10957]. Using this compound

  Plasmodium falciparum thymidylate kinase (PfTMPK) is a key enzyme in pyrimidine nucleotide biosynthesis. 3-Trifluoromethyl-4-chloro-phenyl-urea-α-thymidine has been reported as an inhibitor of Mycobacterium tuberculosis TMPK (MtTMPK). Starting from this point, we designed, synthesized and evaluated a number of thymidine analogues as antimalarials. Both 5′-urea-α- and β-thymidine derivatives were moderate
