LP-922056 是 Notum Pectinacetylesterase 的抑制剂，对人和小鼠的 EC50 值分别为 21 nM 和 55 nM。

Cyclopentolate Hydrochloride 是一种阿托品样毒蕈碱受体拮抗剂，是眼科常用的抗毒蕈碱剂，对睫状肌毒蕈碱受体的 pKB 值为 7.8。

Acetylcysteine (NAC) 是半胱氨酸的 N-乙酰衍生物，是一种 ROS 抑制剂和粘液溶解剂。Acetylcysteine 可诱导细胞凋亡，可用于减少粘液的厚度，还具有抗流感病毒活性。

3-Hydroxykynurenamine, also known as 3-Hydroxy-L-kynurenamine or 3-HKA, is a biogenic amine produced via an alternative pathway of tryptophan metabolism. In vitro, 3-HKA has an anti-inflammatory profile by inhibiting the IFN-γ mediated STAT1 NF-κΒ pathway in both mouse and human dendritic cells (DCs) with a consequent decrease in the release of pro-inflammatory chemokines and cytokines, most notably TNF, IL-6, and IL12p70. 3-HKA has protective effects in an experimental mouse model of psoriasis by decreasing skin thickness, erythema, scaling and fissuring, reducing TNF, IL-1β, IFN-γ, and IL-17 production, and inhibiting generation of effector CD8+ T cells. Similarly, in a mouse model of nephrotoxic nephritis, besides reducing inflammatory cytokines, 3-HKA improves proteinuria and serum urea nitrogen, overall ameliorating immune-mediated glomerulonephritis and renal dysfunction.This compound is unstable in powder form and other related salt forms are recommended.

Palmitoyl Hexapeptide-12 Acetate (Palmitoyl Hexapeptide-12 Acetate (171263-26-6 Free base)) 可以促进胶原蛋白、弹性蛋白和透明质酸的增殖。可用于改善皮肤含水量，增加真皮层厚度，减少细纹。

Myristoyl Tetrapeptide-12 Acetate (Myristoyl Tetrapeptide-12 Acetate (959610-24-3 Free base)) 是肉豆蔻酸和 Tetrapeptide-12 的反应产物，是一种刺激头发和睫毛生长并增强睫毛和 或眉毛外观的肽。 Myristoyl tetrapeptide-12 可以增加角质形成细胞的增殖，改善外观、紧致弹性和皮肤厚度。

PQA-18 是p21激活激酶2（PAK2；IC50 = 10 nM）的有效抑制剂，并作为Ppc-1（产品编号42352）衍生物展现出免疫抑制特性。该化合物能够降低由刀豆A（产品编号14951）刺激的Jurkat T细胞中IL-2的生成（IC50 = 400 nM）。在应用0.1% PQA-18的情况下，NC Nga小鼠模型显示异位性皮炎的严重程度、血清IgE水平及皮肤厚度有所减轻。此外，0.05%的剂量可有效减少该小鼠模型中皮肤神经纤维的密度。PQA-18（4 mg kg）还在大鼠小肠移植模型中显著提高了移植物的存活率。

GM 1489 is a broad-spectrum inhibitor of matrix metalloproteinases (MMPs) with Ki values of 0.002, 0.1, 0.5, 0.2, and 20 μM for MMP-1, MMP-8, MMP-2, MMP-9, and MMP-3, respectively. It reduces 5-aza-2'-deoxycytidine-induced increases in MMP-1, MMP-2, MMP-3, MMP-7, MMP-9, and MMP-14 expression as well as cell invasion in AsPC-1, BxPC-3, Hs766T, MiaPaCa2, and PANC-1 cancer cells. Topical administration of GM 1489 (100 μg) inhibits increases in ear thickness and epidermal hyperplasia induced by phorbol 12-myristate 13-acetate and phorbol dibutyrate (PdiBu) in mice.

KLD-12, a 12-residue self-assembling peptide, displays properties that promote chondrogenic differentiation of bone marrow stromal cells (BMSCs). Moreover, KLD-12 hydrogel can effectively fill full-thickness osteochondral defects in their original location, leading to improved cartilage repair.

Abicipar pegol (AGN-150998, MP0112) 是一种抗VEGFDARPin 分子，DARPin 分子是一类新型的小蛋白，含有工程化的 ankyrin 重复结构域，以高特异性和亲和力与靶蛋白结合。Abicipar pegol 可有效抑制血管生成和血管通透性，通过玻璃体内注射，降低平均视网膜厚度和渗漏面积，用于眼部炎症等相关疾病研究。

Tiger17是一种环状肽，属于tigerinin-RC1和tigerinin-RC2的衍生物，这两种化合物是在螃蟹吃蛙（F. cancrivora）皮肤分泌物中发现的抗微生物肽。在5至20µg/ml的浓度范围内使用时，Tiger17能增加HaCaT角质形成细胞和人类皮肤成纤维细胞的增殖，并且在20µg/ml的浓度下增加HaCaT细胞的迁移。此外，Tiger17还能增加RAW 264.7巨噬细胞的招募及其TGF-β1和IL-6的分泌。在全层皮肤创伤的小鼠模型中，局部应用20µg/ml的Tiger17能加速伤口闭合和重新上皮化的速度。
