HIV-1 Nef-IN-1 is an inhibitor of the HIV-1 Nef protein, effectively competing for Nef-SH3Hck interactions (Kd: 6.7 μM).

SH379, a potent and orally active derivative of 2-methylpyrimidine-fused tricyclic diterpene, serves as an effective agent against late-onset hypogonadism. It significantly enhances the expression of StAR and 3β-HSD, crucial enzymes in testosterone synthesis. Additionally, SH379 stimulates autophagy by modulating the AMPK mTOR signaling pathway [1].

AX-024 hydrochloride (AX-024 HCl) is an cytokine release inhibitor which can strongly inhibit the production of interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), interferon-γ (IFN-γ), IL-10 and IL-17A.

Son of sevenless homolog 1 (Sos1) is a guanine nucleotide exchange factor (GEF) that directs the exchange of Ras-GDP to Ras-GTP by binding to SH3 domains of the growth factor receptor-bound protein 2 (Grb2), leading to the activation of ERK. Ras inhibitory peptide is a synthetic peptide that contains the sequence PVPPR, which corresponds to a region within human Sos1 that interacts with an SH3 domain of Grb2. It specifically blocks the interaction of the GEF with Grb2, preventing an interaction that is essential for Ras activation by receptor tyrosine kinases, including epidermal growth factor receptor.

Compound C108 is an inhibitor of GTPase-activating protein SH3 domain-binding protein 2 (G3BP2). Compound C108 can be used in studies about breast tumors and esophageal squamous cell carcinoma.

AX-024 is a novel chemical compound that acts as an orally available inhibitor of the TCR-Nck interaction. Its primary mechanism of action is the selective inhibition of T cell activation triggered by TCR stimulation. With an IC50 value of approximately 1 nM, AX-024 effectively modulates cell signaling by specifically targeting SH3 domains. Additionally, AX-024 demonstrates desirable characteristics such as low acute toxicity, high potency, and excellent selectivity. Notably, it exhibits strong inhibitory effects on the production of IL-6, TNF-α, IFN-γ, IL-10, and IL-17A.

Ac-Tyr(PO3H2)-Glu-Glu-Ile-Glu-OH TFA (compound 1) is a high-affinity pentapeptide that binds to the src SH2 domain with an IC50 value of approximately 1 µM and inhibits src SH3-SH2: phosphoprotein interactions [1].
