<p>关注流池法溶出仪性能验证的小伙伴赶紧过来围观！在《Dissolution Technology》全新一期期刊中，刊印了一篇题为“Application of Salicylic Acid Tablets in the Performance Verification Test for the Flow-Through Cell Apparatus”（水杨酸校正片在流池法仪器性能验证中的应用）的文章，这对于国内使用流池法溶出仪的业界同仁来说无疑是一个振奋人心的好消息。流池法溶出仪如何执行性能验证一直是业界热门探讨的话题，国际国内均无可参考标准。该文章的发表，为业界指引了可参考的方向。<a href="https://dissolutiontech.com/issues/202405/DT202405_A02.pdf">点击浏览该完整文章</a>。</p>



<p></p>



<h3><span class="has-inline-color has-vivid-cyan-blue-color"><strong>文章摘要：</strong></span></h3>



<p>流通池法是进行缓控释制剂、难溶性药物和诸多特殊剂型（如混悬剂、软胶囊、植入物、微球和脂质体）溶出度测试的优选装置。尽管多年以前药典收载了流池法设备，但没有官方的性能验证测试（PVT）方法。在这项研究中，水杨酸片被用于开发流池法的 PVT 方法。与转篮法和桨法溶蚀和零级释放机制相似，水杨酸片被证明是流池法溶出仪装置 PVT 的一个良好的潜在参考标准。</p>



<p></p>



<p>在实验阶段 I 中，采用实验设计法（DoE）系统研究了四个参数对水杨酸溶出度的影响。其中，片剂加载方式是影响溶出度的最重要参数；流速和流通池内径（ID）也有显著影响；而温度对溶出的影响可以忽略不计。在阶段 II 中，两个测试实验室的四个不同分析员在不同的流通池设备（即四名合作者）进行了重复性和再现性评估，并确定 PVT 的初步验收标准。第&nbsp;II&nbsp;阶段的实验条件是将片剂放置在片剂支架上，流通池内径为 12 mm 装载了玻璃珠，流速为 16 mL/min，温度为 37°C，并在 90 分钟时收集样品。PVT 的再现性通过来自第五个合作者的数据得到证实。</p>

										<content:encoded><![CDATA[
<p>纳米混悬液给药系统是一种新型的给药系统。将药物做成纳米混悬剂有利于增加药物溶出度和提高生物利用度。对于难溶性药物，做成纳米混悬剂，可改善其体内药物动力学行为，提高药效。</p>



<p>不同工艺下的纳米混悬剂，受其处方成分差异、API粒径分布、晶型等影响，溶出行为可能有差异。</p>



<figure class="wp-block-image size-full"><img width="755" height="429" src="/wp-content/uploads/2023/11/圖片-1.jpg" alt="" class="wp-image-18153" srcset="/wp-content/uploads/2023/11/圖片-1.jpg 755w, /wp-content/uploads/2023/11/圖片-1-300x170.jpg 300w" sizes="(max-width: 755px) 100vw, 755px" /><figcaption><sub>（引用自文献[1]）</sub></figcaption></figure>



<p>因此，溶出实验也是纳米混悬剂研究的重要手段。那么，不同制剂工艺下得到的不同批次纳米混悬剂，我们该如何测试它们的溶出行为是否有明显差异？溶出度测试应该如何进行？</p>



<p>从混悬剂溶出实验的角度看，使用桨法，直接将混悬剂投到溶出杯进行溶出实验，似乎是可行的方案。的确，桨法也是混悬制剂中比较常用的方法，但当中可能存在一些问题，影响实验结果，下面列举一个例子：</p>



<p></p>



<p><strong><span class="has-inline-color has-vivid-cyan-blue-color">桨</span></strong><span class="has-inline-color has-vivid-cyan-blue-color"><strong>法 </strong>&#8211; 用移液枪移取一定体积的混悬剂，加入溶出杯中</span></p>



<figure class="wp-block-image size-full"><img width="658" height="508" src="/wp-content/uploads/2023/11/圖片-2.png" alt="" class="wp-image-18154" srcset="/wp-content/uploads/2023/11/圖片-2.png 658w, /wp-content/uploads/2023/11/圖片-2-300x232.png 300w" sizes="(max-width: 658px) 100vw, 658px" /></figure>



<p>在桨法的溶出度实验下，纳米混悬剂的<strong>样品释放速度过快，无法比较不同批次样品的溶出差异</strong>。仔细思考桨法的溶出实验过程，我们可以找出当中的问题：</p>



<ul><li>移液枪移取纳米混悬剂，6个平行样品，加样的时候6杯的加样有时间差，样品的溶出在混悬剂与溶出介质接触时已经开始；</li></ul>



<ul><li>纳米混悬剂加入到溶出杯时的高度、位置可能出现差异，影响溶出结果；</li></ul>



<ul><li>小体积的纳米混悬剂一下子加入到比较大体积的溶出介质中，可能瞬间已完全溶出；</li></ul>



<ul><li>纳米混悬剂分散在溶出介质中，可能在取样时，把没溶出的样品取走，影响溶出结果。</li></ul>



<p></p>



<p><span class="has-inline-color has-vivid-cyan-blue-color"><strong>流池法 </strong>&#8211; 混悬剂被载入流通池，以闭环系统完成实验</span></p>



<p>除了桨法，当然我们可以考虑使用流池法进行实验。流池法是《中华人民共和国药典2020版》新增的方法，因其灵活性和适用范围广泛，在混悬剂的溶出研究中也适用。而<strong>流池法的闭环系统，尤其适用于缓慢释放的样品</strong>，让样品慢慢溶出。</p>



<figure class="wp-block-image size-full"><img width="1006" height="704" src="/wp-content/uploads/2023/11/圖片-4.png" alt="" class="wp-image-18155" srcset="/wp-content/uploads/2023/11/圖片-4.png 1006w, /wp-content/uploads/2023/11/圖片-4-300x210.png 300w, /wp-content/uploads/2023/11/圖片-4-768x537.png 768w" sizes="(max-width: 1006px) 100vw, 1006px" /><figcaption><sub>（粒径：样品1＜样品2）</sub></figcaption></figure>



<p>从流池法的结果中看出，纳米混悬剂缓慢溶出，不同的纳米混悬剂溶出有差异。相比于桨法，流池法有以下优势：</p>



<ul><li>纳米混悬剂被载入流通池中，加样位置相对固定；</li></ul>



<ul><li>纳米混悬剂在实验开始后才与溶出介质接触，才开始溶出的过程；</li></ul>



<ul><li>纳米混悬剂可以被滤膜阻挡在流通池中，溶出过程在流通池中发生；</li></ul>



<ul><li>流通池池子体积较小，并且在溶出原理上其动力更温和，能得到较缓慢的溶出曲线。</li></ul>



<figure class="wp-block-image size-full"><img width="691" height="334" src="/wp-content/uploads/2023/11/螢幕截圖-2023-11-08-下午5.19.11.png" alt="" class="wp-image-18156" srcset="/wp-content/uploads/2023/11/螢幕截圖-2023-11-08-下午5.19.11.png 691w, /wp-content/uploads/2023/11/螢幕截圖-2023-11-08-下午5.19.11-300x145.png 300w" sizes="(max-width: 691px) 100vw, 691px" /></figure>



<p>一篇发布在Molecular Pharmaceutics的文献[1]，也利用流池法进行了纳米混悬剂的体外释放度研究。在溶出过程中，<strong>纳米混悬剂被装载在流通池中的，已溶出的API可以透过滤膜流出流通池，而没有溶出的API则被阻挡在流通池里继续溶出</strong>。</p>



<figure class="wp-block-image size-full"><img width="604" height="468" src="/wp-content/uploads/2023/11/圖片-5.jpg" alt="" class="wp-image-18157" srcset="/wp-content/uploads/2023/11/圖片-5.jpg 604w, /wp-content/uploads/2023/11/圖片-5-300x232.jpg 300w" sizes="(max-width: 604px) 100vw, 604px" /><figcaption><sub>（引用自文献[1]）</sub></figcaption></figure>



<p>对流池法方法进行优化后，可以进行不同样品的溶出实验，有效对比溶出行为的差异。</p>



<p></p>



<figure class="wp-block-image size-full"><img width="427" height="372" src="/wp-content/uploads/2023/11/圖片-6.jpg" alt="" class="wp-image-18158" srcset="/wp-content/uploads/2023/11/圖片-6.jpg 427w, /wp-content/uploads/2023/11/圖片-6-300x261.jpg 300w" sizes="(max-width: 427px) 100vw, 427px" /><figcaption><sub>（引用自文献[1]）</sub></figcaption></figure>



<p>从以上可以看到，流池法在混悬剂的溶出度研究中有一定的优势。以流池法进行纳米混悬剂的溶出度实验，可以更真实地反映混悬剂的释放行为，提高实验结果的可靠性。如果在做混悬剂的溶出实验上碰到问题了，可以尝试一下流池法，或许有意外的收获。</p>

										<content:encoded><![CDATA[
<p>早段时间 ChatGPT 掀起不少声浪，该系统透过 AI 演算学习进行分析，为用户快速寻找答案。近日为了回应市场的需求，百度也发布了生成式 AI 产品&nbsp;—— 文心一言。</p>



<p>近年人工智能的应用已经逐渐走进大众的视野，而在科研领域，基于机器学习的人工智能系统也早已被世界知名的科研机构用于协助科学家完成一项又一项艰深的研究，科研模式的变革早已启动。</p>



<p><span class="has-inline-color has-vivid-cyan-blue-color"><strong>AI + 自动化技术</strong>，<strong>深受世界知名科研公司青睐</strong></span></p>



<p></p>



<p><strong>随机森林算法</strong> &#8211; <strong>普林斯顿大学 x&nbsp;默克</strong></p>



<p>早在 2018 年，普林斯顿大学的 Abigail Doyle 教授就与美国默克 (Merck) 的 Spencer Dreher 博士等合作，以机器学习算法 —— 随机森林算法 (Random Forest Algorithm)，加上通过高通量实验获得的过千项数据进行训练，准确预测了多维变量的 Buchwald-Hartwig 偶联反应产率。Buchwald-Hartwig 反应在药物合成中具有广泛的价值，然而，将这一反应应用于复杂的药物大分子仍然具有挑战性，关键在于当中的五元杂环化合物，如异恶唑这些杂环具有类似药物的特性，但合成并不容易，因此研究团队此次对 Buchwald-Hartwig 偶联反应的研究别具意义。</p>



<p>由于反应物的稀缺，以及化学结构和反应的多维性，过往很难产生足够的数据或从数据库中获得足够完整和一致的数据来进行人工智能的算法训练。随着研究维度的加深，要取得有意义的数据便愈加艰难，而在本次的研究当中，十分关键的是研究人员利用了默克公司较早前建立的高通量反应筛选平台，该高通量实验平台可以在一天内进行超过 1500 个反应，每个反应只需用 0.02 毫克的材料，为研究提供了大量完整及准确的数据基础。</p>



<p></p>



<p><strong>Mobile Robotic Chemist</strong> &#8211; <strong>利物浦大学</strong></p>



<p>除了普林斯顿大学与默克公司合作的研究外，在 2020 年登上 《Nature》 封面的利物浦大学自主研发的 AI 化学家 (Mobile Robotic Chemist)，利用实验室自动化和人工智能的系统，8 天完成 688 次实验，一周时间研究了 1000 种催化配方，并发现了一种新的催化剂。</p>



<div class="wp-block-image"><figure class="aligncenter size-large is-resized"><img src="/wp-content/uploads/2022/10/WeChat_Nov-21_2-772x1024.jpg" alt="" class="wp-image-16881" width="772" height="1024" srcset="/wp-content/uploads/2022/10/WeChat_Nov-21_2-772x1024.jpg 772w, /wp-content/uploads/2022/10/WeChat_Nov-21_2-226x300.jpg 226w, /wp-content/uploads/2022/10/WeChat_Nov-21_2-768x1019.jpg 768w, /wp-content/uploads/2022/10/WeChat_Nov-21_2.jpg 800w" sizes="(max-width: 772px) 100vw, 772px" /><figcaption><meta charset="utf-8"><em><sub>图片源自网络</sub></em></figcaption></figure></div>



<p></p>



<p><strong>自动化合成平台</strong> &#8211; <strong>麻省理工学院</strong></p>



<p>无独有偶，登上 《Science》 的美国麻省理工学院 (MIT) 研究人员也开发了一种结合 AI 设计合成路线和机器人执行的自动化合成平台。</p>



<p>实验中，利用数据库中的反应训练了人工智能算法，为指定分子提出合成路线，包括反应条件，并根据步骤数量和预测产量来评估哪条路径是最佳。</p>



<p>同时，MIT 研究人员在新开发的系统上结合了三个主要步骤：首先，由人工智能指导的软件提出了合成分子的途径，然后专家化学家审查这条路线并将其细化为化学 “配方”，最后将配方发送到机器人平台，自动组装硬件并执行反应构建分子。</p>



<p>此外，该系统拥有一个灵活的机器人手臂，能够执行所有合成操作流程，实现自动化合成，并成功用于 15 个化学小分子药物的合成路线设计和自动化合成。</p>



<p></p>



<p></p>



<p><strong>RoboRXN &#8211; IBM</strong></p>



<p>IBM 研究中心也与实验室自动化的专业品牌 Chemspeed 合作，建立了以 AI 驱动的 RoboRXN 化学实验室。这一实验室融合了云技术、AI 和自动化高通量实验工作站，改变了化学家的工作方式，极大地加速了研发效率。</p>



<figure class="wp-block-image size-large is-resized"><img src="/wp-content/uploads/2022/10/WeChat_Nov-21_4-1024x526.png" alt="" class="wp-image-16889" width="840" height="431" srcset="/wp-content/uploads/2022/10/WeChat_Nov-21_4-1024x526.png 1024w, /wp-content/uploads/2022/10/WeChat_Nov-21_4-300x154.png 300w, /wp-content/uploads/2022/10/WeChat_Nov-21_4-768x395.png 768w, /wp-content/uploads/2022/10/WeChat_Nov-21_4.png 1080w" sizes="(max-width: 840px) 100vw, 840px" /><figcaption><em><sub>图片源自网络</sub></em></figcaption></figure>



<p>以上的研究都说明了人工智能技术在科学研究领域的巨大潜力，但是纵观所有的人工智能在化学研究上的应用案例，无一例外的都离不开自动化实验技术。作为 “硬件设施”，自动化技术执行 AI &nbsp;(“软件”) 提供的最优化实验方案，并提供大量的完整且准确的数据。作为 “软件设施”，人工智能系统可以利用这些数据进行训练及演算，快速预测研究结果，并完成实验的迭代并优化过程，帮助科学家快速找到有价值的研究方向，减少大量的实验时间和研究成本。科研的变革已然启动，未来，人工智能的技術必然将更广泛应用在科学研究领域，推动科学的进步。</p>

				<p>原料药在医药产业中各个环节中都十分关键，尤其在项目进入临床阶段后，对原料药的需求更大。原料药的生产过程十分复杂，而且容易受环境参数如: 温度、湿度、压力等等的影响，有些原材料更有一定危险性，因此在进行原料药的扩大工艺时，除了要考虑其质量、经济效益外，更要考虑其安全性。通过反应筛选进行原料药的工艺开发，可以寻找最佳的反应条件、最佳的催化体系，实现反应选择性的优化，并获得尽可能低的杂质含量目标产物。</p>					</div>

				<section><p>在药物开发的过程中，AbbVie 研究团队要从数千个合成的化学分子中筛选出合适的候选分子再进行研究，更要面对在亚毫克规模下准备数百个固体样品，因此必须从这些瓶颈中找出新突破，以克服微量固体化学试剂精确称量及分配的问题。</p></section><section><p>研究人员借鉴了制药行业常用的干粉涂层技术，将小的粒子与较大的主粒子 (10 &#8211; 100 倍) 混合，并施加机械外力强化混合效果，最终使小粒子通过分子间作用力粘附在大主粒子表面。</p><p>在评估了几种材料后，研究人员最后因玻璃珠具有好的流动性、化学惰性，以及规则圆形的光滑表面等优点，有利试剂分布均匀，所以选用了玻璃珠作为载体，负载不同的固体试剂。</p></section><section><p>研究人员更通过超声处理将玻璃珠与固体试剂混合，这些携带试剂的玻璃珠 (ChemBeads) 直径约 250 微米，化学试剂仅占其质量的 1% &#8211; 20%，通过玻璃珠放大试剂的体积，利于日常称量操作，重量能较准确地控制，可用于分配极微量的试剂，误差可以控制在 ±10% 以内，足够应付筛选反应实验。同时，测试证明玻璃珠可负载超过 300 种不同固体试剂，当中包括对空气或水分敏感的化学试剂。在稳定性方面，更可保持稳定 18 个月以上。 </p></section>					</div>
