Protein protein interactions (PPI) have pivotal roles in life processes. The studies showed that aberrant PPI are associated with various diseases. However, the design of modulators targeting PPI still faces tremendous challenges, such the difficult PPI interfaces for the drug design, lack of ligands reference, lack of guidance rules for the PPI modulators development and high-resolution PPI proteins structures.

The PPI Library comprises molecules of various sizes, frameworks, and shapes ranging from fragment-like entities to macrocyclic derivatives designed as secondary structure mimetics or as epitope mimetics. The designs cover β-turn / loop mimetics and α-helix mimetics. Since helices present at the interface in 62% of all protein-protein interactions. This library focused on designs including mimics with the substitution geometry of an a-helices, as well as designs that mimic the location of “hot-spot” side chains in helix-mediated PPIs.

疼痛是一种由组织损伤刺激引起的痛苦感知。根据国际疼痛研究协会（IASP）的定义，疼痛指“与实际或潜在组织损伤相关的，或用于描述此类损伤的不愉快的感觉和情绪体验”。

疼痛通常根据其位置、持续时间、潜在原因和强度等进行分类。分类包括急性和慢性疼痛、肌肉疼痛和神经疼痛等。疼痛是大多数疾病的主要症状，严重影响患者的生活质量和机体功能。在疼痛的药物治疗中，传统上通常使用抗炎药和阿片类镇痛剂，但副作用较大。近年来，靶向ERK/MAPK通路等靶点的靶向药物逐渐成为研究热点。

MCE可以提供2,216种靶向疼痛关键靶点的化合物，是进行疼痛相关研究及抗疼痛药物开发的有用工具。

尽管脑癌只占所有肿瘤发病人数的2%，但由于存在预后差、死亡率高、复发率高等问题，被临床重视。脑癌可被分为原发性脑癌和继发性脑癌。根据发病部位不同，脑癌还可被分为：脑胶瘤、垂体腺瘤、神经鞘瘤、颅咽管瘤，脑膜瘤等。其中胶质瘤是最常见的原发性脑肿瘤，约占所有脑部肿瘤的 1/3。目前，脑癌缺乏精准靶向治疗药，仍存在着极大的临床需求并未被满足。随着高通量筛选技术的不断发展，通过筛选靶向 PKC、PD-1、c-Met、PARP 等靶点化合物，或许能够帮助开发出有效的抗脑癌药物。

MCE 收录了 1,608 个具有明确或潜在抗脑癌活性的小分子化合物，是研究脑癌相关病理机制或进行抗脑癌药物开发的重要工具。
