本發(fā)明屬于藥物化學(xué)及藥物合成技術(shù)領(lǐng)域,具體涉及一類孿藥型hmg-coa還原酶抑制劑及其合成方法。
背景技術(shù):
血漿中總膽固醇、低密度脂蛋白、甘油三酯中其中一種或多種水平升高,即為高脂血癥。血脂水平過高,可直接引起一些嚴(yán)重危害人體健康的疾病,如動(dòng)脈粥樣硬化、冠心病、胰腺炎等。臨床上用于治療高血脂癥的藥物主要分為兩大類,以降低血清總膽固醇和ldl膽固醇為主的有他汀類和樹脂類,以降低血清三酰甘油為主的藥物有貝特類和煙酸類。
貝特類降脂藥,又稱苯氧芳酸類降脂藥,可通過增強(qiáng)脂蛋白脂酶的活性加速脂蛋白的分解,同時(shí)也能減少肝臟中脂蛋白的合成,從而降低血脂。這類藥物的突出作用是顯著降低甘油三酯。煙酸類藥物屬b族維生素,當(dāng)用量超過其作為維生素作用的劑量時(shí),可有明顯的降脂作用。
臨床上使用最廣泛的調(diào)脂藥物是他汀類,它是hmg-coa還原酶抑制劑,通過可逆性的競(jìng)爭(zhēng)輔酶使hmg-coa不能轉(zhuǎn)化為甲羥戊酸,從而抑制內(nèi)源性膽固醇合成、降低低密度脂蛋白、升高高密度脂蛋白。
氟伐他汀單獨(dú)或聯(lián)合治療混合型高脂血癥研究表明氟伐他汀與苯扎貝特合用有效降低ldl-c水平24%,降低tg水平38%,升高h(yuǎn)dl-c水平22%,優(yōu)于單藥治療時(shí)的降脂療效。辛伐他汀聯(lián)合非諾貝特治療高脂血癥研究(safari研究)納入618例致動(dòng)脈粥樣硬化血脂異常的患者,分別接受辛伐他汀聯(lián)合非諾貝特和單用辛伐他汀治療。結(jié)果顯示兩藥聯(lián)合治療較單一治療進(jìn)一步顯著降低tg23%和ldl-c54%,同時(shí)進(jìn)一步顯著升高h(yuǎn)dl-c水平89%。上述研究表明,他汀與貝特聯(lián)合能達(dá)到協(xié)同的調(diào)脂作用。煙酸與降脂常用藥他汀類聯(lián)合在全面調(diào)脂、減少心血管剩留危險(xiǎn)、藥物經(jīng)濟(jì)學(xué)評(píng)價(jià)等方面也具有明顯優(yōu)勢(shì)。
綜所上述,貝特類、煙酸類化合物與他汀類化合物聯(lián)用有利于更好的降低血脂,利用貝特類、煙酸類化合物與他汀類化合物拼接合成新的降血脂化合物也具有了令人期待的意義。

材料和儀器。hmg-coareductaseassaykit(美國(guó)sigmaaldrich公司此試劑盒中包括:hmgr,hmg-coa,nadp-h,緩沖液,陽(yáng)性對(duì)照溶液),輔助材料為96孔板、超純水、精密移液器(1-100μl,10-1000μl,2-20μl和0.5-2μl各一把)及其配套一次性槍頭,酶標(biāo)儀(配計(jì)算機(jī)系統(tǒng))
藥劑配制和準(zhǔn)備。將10ml的5倍濃度緩沖液稀釋成1倍緩沖液(即10ml的5倍液加40ml的超純水),在用96孔板的情況下,1ml的1倍液可進(jìn)行5個(gè)樣的測(cè)試,保存于冰中待用,剩余的5倍緩沖液于-20℃保存。25mg的nadph需要補(bǔ)充1.5ml的1倍緩沖液,混合均勻-20℃保存。
測(cè)試樣品準(zhǔn)備。按要求稱取大約1-5mg的樣品,移液槍精確加入計(jì)算量的0.1%的naoh溶解到蒸餾水/四氫呋喃混合溶劑(體積比1:1)所得溶液,低溫超聲約5mins后溶解完全,所得溶液即為0.01mol/l的測(cè)試樣品原始溶液。
依次稀釋得到10-4,10-5,10-6,10-7,10-8,10-9六個(gè)濃度冷藏備用。
方法和流程
解凍:解凍酶需要在冰上隨周圍環(huán)境冷卻,盡量不要將酶放在冰上超過60min,因?yàn)榉胖脮r(shí)間過長(zhǎng)會(huì)導(dǎo)致酶的活性降低。其他解凍可在室溫下進(jìn)行,一旦解凍應(yīng)保存在冰上。
儀器調(diào)校:實(shí)驗(yàn)開始前將溫度調(diào)至37℃,吸收波長(zhǎng)為340nm,準(zhǔn)備好動(dòng)態(tài)程序。96孔板樣品每20秒讀一次數(shù),總計(jì)10-20min。
根據(jù)以下kit提供的表格及流程加入合適體積的反應(yīng)液
測(cè)試步驟:
a.在每個(gè)孔內(nèi)加入定量的1倍緩沖液;
b.加待測(cè)樣品的于除空白和陽(yáng)性對(duì)照以外的孔內(nèi)
c.加補(bǔ)充過緩沖液的nadph于每個(gè)孔內(nèi)
d.加底物hmg-coa于每個(gè)孔內(nèi)
e.加酶hmgr于除空白以外的孔內(nèi)
f.將反應(yīng)液混合均勻,尤其用96孔板測(cè)樣時(shí)至少要在測(cè)第一次吸光地之前強(qiáng)力攪拌10秒
g.開啟動(dòng)態(tài)程序,觀察吸光度的變化
從計(jì)算機(jī)程序中點(diǎn)選有信息的數(shù)據(jù)點(diǎn),所得數(shù)據(jù)即為測(cè)試原始數(shù)據(jù)。
數(shù)據(jù)處理原理。
根據(jù)kit介紹的方法進(jìn)行活性測(cè)試,得到吸光度下降曲線,下降的斜率表明了不同樣品對(duì)hmgr酶的抑制效果,對(duì)所得的斜率曲線進(jìn)行數(shù)學(xué)處理和擬合,根據(jù)kit的技術(shù)支持,由以下公式計(jì)算活性數(shù)據(jù):
其中:參數(shù)12.44表示12.44mm/cm,由于nadph在340nm下的減弱系數(shù)我為6.22mm/cm,在反應(yīng)機(jī)理中未兩倍的nadph,故為12.44
tv為反應(yīng)液的總體積,96孔板為0.2ml
v表示還原酶的體積,即在每次測(cè)試中所用的酶的體積
0.6表示使用mg-protein單位(mgp)/ml下的濃度,一般為0.50-0.70,這里試劑盒提供的濃度為0.6
lp表示光路寬度,96孔板為0.55cm
unit定義為在37℃下每min1μmol的nadph轉(zhuǎn)化為nadp+,具體單位為μmol/min/mg蛋白質(zhì)
表示340nm處紫外吸光度隨時(shí)間的變化率。這段時(shí)間就是上面強(qiáng)調(diào)的勻速反應(yīng)階段這段時(shí)間,因此在實(shí)際選取數(shù)據(jù)點(diǎn)(吸光度,時(shí)間)時(shí),要通過做曲線圖的方法來(lái)找出這段時(shí)間。
定義抑制率為
其中[活性數(shù)據(jù)activity]表示依據(jù)公式對(duì)應(yīng)測(cè)試計(jì)算出的activity活性數(shù)值,[活性數(shù)據(jù)sample]表示加入抑制劑樣品后的活性數(shù)值。附表后的他汀對(duì)照為同一批測(cè)試值,作為測(cè)試的陽(yáng)性對(duì)照。
部分所合成化合物對(duì)hmg-coa還原酶(hmgr)的酶活性的抑制作用,實(shí)驗(yàn)結(jié)果如下表1所示。
