  In vivo evaluation of oral anti-tumoral effect of 3,4-dihydroquinazoline derivative on solid tumor

  摘要：

  An extension of our previously reported 3.4-dihydroquinazoline derivative is investigated. Oral anti-tumoral activity of 3,4-dihydroquinazoline derivative (KYS05090) as potent and selective T-type calcium channel blocker was in vivo evaluated against A549 xenograft in BALB/c(nu/nu) nude mice. The rate of tumor volume increment in mouse model with KY505090-treated group was remarkably slower than that of control group. With respect to tumor weight, it exhibited 60% and 67% tumor growth inhibition through oral administration of 1 and 5 mg/kg of bodyweight, respectively, compared to control and was more potent than paclitaxel (53%). In addition, KYS05090 (10 and 50 mg/kg, po) was found to have a marked analgesic effect in acetic acid-induced writhing test, whereas it did not show any effect on hot plate test.

  3,4-二氢喹唑啉衍生物抑制胆碱酯酶的活性

  摘要：

  体外测试了一系列3,4-二氢喹唑啉衍生物，这些衍生物由我们的化学文库中选自不同化合物的化合物和新合成的化合物组成，分别测试了它们对乙酰胆碱酯酶（AChE，来自鳗鱼）和丁酰胆碱酯酶（BChE，来自马血清）酶。发现大多数化合物显示出弱的AChE和强的BuChE抑制活性。尤其是，化合物8b和8d是该系列产品中针对BChE的最具活性的IC 50对BChE的亲和力值分别为45 nM和62 nM，以及分别高146和161倍。为了了解这些化合物的出色活性，进行了分子对接模拟，以更好地了解3,4-二氢喹唑啉衍生物的结合机理。如我们所料，化合物8b和8d以比AChE更好的相互作用能值与BChE的催化阴离子位点（CAS）和外围位点（PS）结合。此外，两种化合物的非竞争性/混合型抑制作用在动力学研究中进一步证实了它们的双重结合性质。

  The intensive SAR study of 3,.4-dihydroquinazoline series led to the most potent compound 10 (KYS05090: IC50 = 41 +/- 1 nM) against T-type calcium channel and its potency is nearly comparable to that of Kurtoxin. As a small organic molecule, this compound showed the highest blocking activity reported to date. (c) 2007 Elsevier Ltd. All rights reserved.

  The growth inhibition of human cancer cells via T-type Ca2+ channel blockade has been well known. Herein, a series of new 3,4-dihydroquinazoline derivatives were synthesized via a brief SAR study on KYS05090 template and evaluated for both T-type Ca2+ channel (Ca(v)3.1) blockade and cytotoxicity on three human ovarian cancer cells (SK-OV-3, A2780 and A2780-T). Most of compounds except 6i generally exhibited more potent cytotoxicity on SK-OV-3 than mibefradil as a positive control regardless of the degree of T-type channel blockade. In particular, eight compounds (KYS05090, 6a and 6c-6h) showing strong channel blockade exhibited almost equal and more potent cytotoxicity on A2780 when compared to mibefradil. On A2780-T paclitaxel-resistant human ovarian carcinoma, two compounds (KYS05090 and 6d) were 20-fold more active than mibefradil. With respect to cell cycle arrest effect on A2780 and A2780-T cells, KYS05090 induced large proportion of sub-G(1) phase in the cell cycle progression of A2780 and A2780-T, meaning the induction of cancer cell death instead of cell cycle arrest via blocking T-type Ca2+ channel. Among new analogues, compounds 6g and 6h induced cell cycle arrest at G(1) phase of A2780 and A2780-T cells in dose-dependent manner and exhibited strong anti-proliferation effects of ovarian cancer cells by blocking T-type Ca2+ channel. Furthermore, 6g and 6h possessing strong cytotoxic effects could induce apoptosis of A2780 cells, which was detected by confocal micrographs using DAPI staining. (C) 2013 Elsevier Ltd.

  In order to further clarify the role of T-type Ca2+ channels in cell proliferation, we have measured the growth inhibition of human cancer cells by using our potent T-type Ca2+ channel blockers. As a result, KYS05090, a most potent T-type Ca2+ channel blocker, was found to be as potent as doxorubicin against some human cancer cells without acute toxicity. Therefore, this letter provides the biological results that T-type calcium channel is important in regulating the important cellular phenotype transition leading to cell proliferation, and thus novel T-type Ca2+ channel blocker presents new prospects for cancer treatment.
