<strong>泰菲乐</strong>（<strong>Tafinlar</strong>，通用名：<strong>达拉非尼/Dabrafenib</strong>）是一种强效、高选择性的口服ATP竞争性<strong>[[BRAF]]</strong>激酶抑制剂。它主要针对携带<strong>[[BRAFV600]]</strong>突变（如V600E、V600K）的肿瘤细胞，通过阻断MAPK信号通路来抑制肿瘤增殖。在2026年的精准肿瘤学实践中，泰菲乐通常与MEK抑制剂<strong>[[曲美替尼]]</strong>联合使用，作为治疗携带BRAF突变的<strong>[[晚期黑色素瘤]]</strong>、<strong>[[非小细胞肺癌]]</strong>及<strong>[[间变性甲状腺癌]]</strong>的标准治疗方案。泰菲乐的出现显著改善了携带特定基因突变患者的生存预后，是实体瘤精准靶向治疗的基石药物之一。<br />

<p style="margin: 15px 0; text-align: justify;"><br />
泰菲乐的作用核心在于对突变型BRAF激酶活性的特异性干扰，其分子药理过程如下：<br />
</p><br />
<ul style="padding-left: 25px; color: #334155;"><br />
<li style="margin-bottom: 12px;"><strong>ATP竞争抑制：</strong>泰菲乐能够特异性嵌入BRAFV600激酶结构域的ATP结合位点，阻止磷酸基团转移，使BRAF蛋白失去催化下游<strong>[[MEK]]</strong>蛋白的能力。</li><br />
<li style="margin-bottom: 12px;"><strong>高选择性杀伤：</strong>该分子对V600E突变蛋白的抑制效力比野生型高出数百倍，有效降低了对正常细胞信号传导的干扰。</li><br />
<li style="margin-bottom: 12px;"><strong>抑制MAPK通路：</strong>通过切断RAS-RAF-MEK-ERK信号级联，诱导肿瘤细胞发生G1期细胞周期停滞并启动凋亡程序。</li><br />
<li style="margin-bottom: 12px;"><strong>联合拦截策略：</strong>与曲美替尼联用可实现对MAPK通路的“双重打击”，防止旁路激活并显著延缓<strong>[[获得性耐药]]</strong>的发生。</li><br />

<li style="margin-bottom: 12px;"><strong>皮肤病变评估：</strong>需警惕新发皮肤原发肿瘤（如<strong>[[鳞状细胞癌]]</strong>）。联合曲美替尼可显著降低此类风险，但仍需定期进行专业皮肤科检查。</li><br />
<li style="margin-bottom: 12px;"><strong>视力与心脏监测：</strong>由于对信号通路的抑制，少数患者可能出现葡萄膜炎或LVEF下降，需定期随访相关指标。</li><br />
