<strong>[[夫拉平度]]</strong>（<strong>[[Flavopiridol]]</strong>，又名<strong>[[阿伏西地]]</strong>/<strong>[[Alvocidib]]</strong>）是全球首个进入临床试验的<strong>[[多靶点细胞周期蛋白依赖性激酶]]</strong>（[[CDK]]）抑制剂。作为一种源自植物生物碱[[Rohitukine]]的半合成黄酮类化合物，它能强效竞争性结合[[CDK1]]、[[CDK2]]、[[CDK4]]、[[CDK6]]以及<strong>[[CDK9]]</strong>的[[ATP]]结合口袋。在2026年的血液肿瘤治疗体系中，[[夫拉平度]]主要通过抑制[[CDK9]]干扰<strong>[[P-TEFb]]</strong>复合物，进而下调[[MCL-1]]等抗凋亡蛋白的转录，在<strong>[[急性髓系白血病]]</strong>（[[AML]]）及<strong>[[慢性淋巴细胞白血病]]</strong>（[[CLL]]）的联合化疗方案中展现出独特的诱导凋亡价值。<br />

<br />
<p style="margin: 15px 0; text-align: justify;"><br />
[[夫拉平度]]具有双重抗肿瘤机制，不仅能够锁定细胞周期，更能从根源阻断抗凋亡信号：<br />
</p><br />
<br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>细胞周期阻滞（Pan-CDK抑制）：</strong> 通过抑制[[CDK1]]、[[CDK2]]和[[CDK4/6]]，[[夫拉平度]]能将癌细胞拦截在[[G1/S]]期和[[G2/M]]期交界处，直接抑制肿瘤细胞增殖。</li><br />
<li style="margin-bottom: 12px;"><strong>转录抑制（CDK9核心效应）：</strong> [[CDK9]]是[[正转录延伸因子b]]（[[P-TEFb]]）的核心组分。[[夫拉平度]]抑制[[CDK9]]后，阻止了[[RNA聚合酶II]]的[[C-末端结构域]]（[[CTD]]）磷酸化。</li><br />
<li style="margin-bottom: 12px;"><strong>快速下调[[MCL-1]]：</strong> 由于[[MCL-1]]蛋白的[[mRNA]]半衰期极短，转录受阻会导致[[MCL-1]]水平迅速下降，使肿瘤细胞对凋亡信号极端敏感，从而克服耐药。</li><br />

<p style="margin: 15px 0; text-align: justify;"><br />
[[夫拉平度]]的临床应用由于其强效的诱导凋亡能力，需高度关注安全性管理：<br />
</p><br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>[[肿瘤溶解综合征]]（[[TLS]]）防控：</strong> [[夫拉平度]]引起的肿瘤细胞大规模死亡极易诱发致命的[[TLS]]。临床需严格进行水化、[[碱化]]及[[别嘌醇]]预处理。</li><br />
<li style="margin-bottom: 12px;"><strong>给药剂量逻辑：</strong> 现代方案倾向于采用“[[推注-输注]]”（[[Bolus-Infusion]]）模式，以确保在短时间内达到抑制[[CDK9]]所需的血药浓度峰值。</li><br />
<li style="margin-bottom: 12px;"><strong>针对[[MCL-1]]依赖人群：</strong> 通过[[BH3谱图]]（[[BH3 Profiling]]）检测肿瘤对[[MCL-1]]的依赖程度，是筛选[[夫拉平度]]获益人群的最佳策略。</li><br />
