  Synthesis and biological activity of 3,4-dihydroquinazolines for selective T-type Ca2+ channel blockers

  摘要：

  We have synthesized 3,4-dihydroquinazoline derivatives for the potent and selective T-type Ca2+ channel blockers and evaluated for their inhibitory activities against two subtypes T-type Ca2+ channels and N-type Ca2+ channels. Among them, 5b (KYS05044, IC50 = 0.56 +/- 0.10 muM) was identified as potent T-type Ca2+ channel blocker with in vitro selectivity profile at meaningful level (T/N-type, SI = >100).

  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。

  Two piperazine-containing 3,4-dihyroquinazolines (BK10007S/8S) have been synthesized, based on our previous work on the synthesis and antitumoral activity of 3,4-dihyroquinazolines. After evaluating them for T-type calcium channel blocking effect and in vitro anti-cancer effect, they were profiled for acute and repeat dose toxicity (40 mg/kg, 2 weeks) to BALB/c mice. BK10007S/8S were further in vivo evaluated against human pancreatic MIA PaCa-2 carcinoma in $BALB/c^nu/nu}$ nude mice, which exhibited 54 and 61% tumor growth inhibition through 57-day oral administration of 2 mg/kg of body weight, respectively.

  基于我们对3,4-二氢喹唑啉合成及其抗癌活性的先前工作，合成了两种含有哌嗪的3,4-二氢喹唑啉（BK10007S/8S）。经过对其T型钙通道阻断效应和体外抗癌效应的评估后，对其在BALB/c小鼠中进行了急性和重复剂量毒性（40 mg/kg，2周）的轮廓分析。进一步在体内评估了BK10007S/8S对人类胰腺癌MIA PaCa-2在$BALB/c^nu/nu}$裸鼠中的作用，通过57天口服给药2 mg/kg体重，分别显示出54%和61%的肿瘤生长抑制。

  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.

  3,4-Dihydroquinazoline analogues substituted by N-methyl-N-(5-pyrrolidinopentyl)amine at the 2-position were synthesized and their blocking effects were evaluated for T- and N-type calcium channels. Compound 11b (KYS05080), compared to mibefradil (IC50 = 1.34 0.49 mu M), was about 5-fold potent (IC50 = 0.26 +/- 0.01 mu M) for T-type calcium channel (alpha(1)G) blocking and its selectivity of T/N-type was also improved (7.5 versus 1.4 of mibefradil).
