  Pyrimethamine conjugated histone deacetylase inhibitors: Design, synthesis and evidence for triple negative breast cancer selective cytotoxicity

  摘要：

  Signal transducer and activator of transcription 3 (STAT3) is an oncogenic transcription factor which has been recognized as a promising cancer therapeutic target. Small molecule pyrimethamine (PYM) is a known direct inhibitor of activated STAT3 and it is currently under clinical trial. Also, histone deacetylase (HDAC) inhibition has been shown to indirectly attenuate STAT3 signaling through inhibition of STAT3 activation. Herein we described the design and biological profiling of two classes of PYM-conjugated HDAC inhibitors (HDACi). We observed that the class I PYM-HDACi compounds 12a-c potently inhibited HDACs 1 and 6 in cell free assays while a lead class II PYM-HDACi compound 23 showed a strong HDAC 6 selective inhibition. In a cell-based assay, 12a-c are preferentially cytotoxic to MDA-MB-231, a TNBC cell line that is highly STAT3-dependent, while 23 showed no such selective toxicity. Subsequent target validation studies revealed that a representative class I PYM-HDACi compound 12c elicited a signature of HDAC and STAT3 pathway inhibition intracellularly. Collectively, these data suggest that PYM-HDACi compounds are promising leads to develop targeted therapy for TNBC.

  Ametoctradin是一种有效的Q Ø线粒体呼吸复合物III的位点抑制剂

  摘要：

  Ametoctradin是BASF正在研发的一种新型卵菌特异性杀菌剂。它是线粒体呼吸作用中bc 1复合物的有效抑制剂。但是，其详细的作用机理仍然未知。在目前的工作中，首先通过整合分子对接，MD模拟和MM / PBSA计算发现了met虫oct的结合模式，这表明a虫radi应该是bc 1复合物的Q o部位抑制剂。随后，设计并合成了一系列新的1,2,4-三唑并[1,5- a ]嘧啶衍生物，以进一步了解取代基对1,2,4-三唑并[1] 5和6位的影响。 ，5-一]嘧啶。计算出的新合成类似物作为Q o部位抑制剂的结合自由能（ΔG cal）与它们的实验结合自由能（ΔG exp）很好地相关（R 2 = 0.96 ）。已成功鉴定出两种化合物（4a和4c）对猪SQR的抑制活性高于阿美他汀。从本研究中获得的结构和力学见解将为将来设计新的有前途的bc 1抑制剂提供有价值的线索。

  The reduced binding of pyrimethamine to Ser 108Asn (S108N) mutants of parasite dihydrofolate reductase (DHFR), which forms the basis of resistance of Plasmodium falcipartum to pyrimethamine, is largely due to steric constraint imposed by the bulky side chain of N108 on Cl of the 5-p-Cl-phenyl group. This and other S108 mutants with bulky side chains all showed reduced binding to pyrimethamine and cycloguanil. Less effect on binding to some bulky mutants was observed for trimethoprim, with greater flexibility for the 5-substituent. S108N DHFR also binds poorly with other pyrimethamine derivatives with bulky groups in place of the p-Cl, and the binding was generally progressively poorer for the double (C59R+S108N) mutant. Removal of the p-Cl or replacement with m-Cl led to better binding with the mutant DHFRs. Pyrimethamine analogues with unbranched hydrophobic 6-substituents showed generally good binding with the mutant DHFRs. A number of compounds were identified with high affinities for both wild-type and mutant DHFRs, with very low to no affinity to human DHFR. Some of these compounds show good antimalarial activities against pyrimethamine-resistant P. falciparum containing the mutant DHFRs with low cytotoxicity to three mammalian cell lines.

  日期：2008.3.1

  [GRAPHICS]A variety of functionalized N-alkoxyindole-3-carbonitrile derivatives are achieved under remarkably mild conditions by applying a FeCl3-mediated intramolecular heterocyclization of 3-alkoxyimino-2-arylalkylnitliles. This novel synthesis allows the N-moiety on the side chain to be annulated to the benzene ring as the final synthetic step, which enables the functionalization of the benzenoid portion of the indole at an early stage of the synthesis.
