GJ103 sodium salt is an active analog of GJ072, a read-through compound. It has been shown to reduce the surface tension of aqueous solutions, which makes it easier for molecules to move through the solution. It has also been shown to reduce the viscosity of aqueous solutions, which makes it easier for molecules to move through the solution. Additionally, it has been shown to reduce the pH of aqueous solutions, which can have a variety of effects on the biochemical and physiological processes of living organisms.

ATM Inhibitor-1 is a highly potent, selective, and orally active ATM inhibitor (IC50: 0.7 nM) with anti-tumor activity. It exhibits weak activity against mTOR (IC50, 21 μM), DNAPK (IC50, 2.8 μM), PI3Kα (IC50, 3.8 μM), PI3Kβ (IC50, 10.3 μM), PI3Kγ (IC50, 3 μM), and PI3Kδ (IC50, 0.73 μM).

Tuvusertib (M1774) is an orally available ataxia telangiectasia and Rad3-related (ATR) kinase inhibitor (Ki< 1 µΜ) with selective and potentially antitumor activity.Tuvusertib selectively inhibits ATR activity and blocks downstream phosphorylation of serine/threonine protein kinase checkpoint kinase 1 (CHK1), thereby inhibits DNA damage checkpoint activation, disrupting DNA damage repair and inducing apoptosis in tumor cells.
