9-Methoxycanthin-6-one 是存在于完整植株和不同外植体的愈伤组织中的 Canthin-6-one 生物碱，具有抗肿瘤作用。

Methionylmethionine (Met-Met) 显著促进了乳腺外植体中 α-s1 酪蛋白 (αS1-CN) 的表达，通过增加细胞内底物的可用性以及激活 JAK2-STAT5 和 mTOR 介导的信号通路。

SB-505124 hydrochloride (SB505124 hydrochloride) 是一种可口服且具有选择性和高效性的 TGF-βI 型受体(ALK4，ALK5，ALK7) 抑制剂，对 ALK4，ALK5 的IC50值分别为 129 nM 和 47 nM。SB-505124 hydrochloride 抑制滑膜外植体产生 IL-6，通过降低 Il17a 和 Rorc 基因表达以及 IL-17 蛋白的产生减少小鼠 Th17 分化。SB-505124 hydrochloride 可用于研究结直肠癌。

Quininib是一种选择性的CysLTR1和CysLTR2拮抗剂， IC50 分别为1.2和52μM，具有抗血管生成和抗肿瘤的作用。

DPC-AJ1951 is a peptide agonist of the parathyroid hormone (PTH) PTH-related peptide receptor (PPR; EC50 = 0.15 nM in HEK293 cells expressing human PPR). It induces cAMP production in SAOS-2 and UMR106 cells that endogenously express human and rat PPR, respectively (EC50s = 2.2 and 1.1 nM, respectively). DPC-AJ1915 stimulates osteoclast-mediated bone resorption in fetal rat long-bone explant cultures and increases collagen synthesis and cell proliferation in neonatal mouse parietal bone explants. In vivo, DPC-AJ1951 normalizes serum calcium levels in thyroidparathyroidectomized rats.

Highly potent and selective MMP13 inhibitor (IC50 = 6.9 pM). Exhibits >2600-fold selectivity for MMP13 over related MMPs. Inhibits degradation of bovine nasal septum cartilage explants in vitro . Orally bioavailable. Nara et al (2014) Thieno[2,3-d]pyrimidine-2-carboxamides bearing a carboxybenzene group at 5-position: highly potent, selective, and orally available MMP-13 inhibitors interacting with the S1 binding site.

AZ1366 is a potent tankyrase inhibitor that enhances irinotecan activity in tumors that exhibit elevated tankyrase and irinotecan resistance. Combination AZ1366 and irinotecan achieved greater anti-tumor effects compared to monotherapy. Activity was limited to CRC explants that displayed irinotecan resistance and increased protein levels of tankyrase and NuMA.

RO314724 is a HDAC inhibitor. RO314724 is also a a reversible, tightly binding, MMP inhibitor with a Ki of 26 nm. Matrix metalloproteinases (MMPs) belong to the key enzymes of the proteolytic destruction of cartilage matrix during chronic rheumatic diseases. Ro314724 displayed MMP-proteoglycanase inhibitory activity both in vitro and ex vivo and proved to be not harmful to the morphology, viability and proteoglycan biosynthesis of bovine articular cartilage explants.
