GDC-0425 (RG-7602) is a potent and highly selective inhibitor of Checkpoint kinase 1 (Chk1). This product blocks DNA damage-induced cell cycle arrest by inhibiting Chk1 activity, forcing damaged cells into mitosis and ultimately leading to apoptosis. Research indicates that the activity of GDC-0425 is modulated by the Ras-MEK signaling pathway, and it significantly enhances tumor regression when combined with DNA-damaging agents like Gemcitabine.

Lidocaine (Alphacaine) is an amide local anesthetic with anti-inflammatory properties in vitro and in vivo. It has this functions perhaps due to an attenuation of intracellular adhesion molecule-1 (ICAM-1), pro-inflammatory cytokines, and reduction of neutrophils influx.

TAC (TERT activator compound) is a TERT (telomerase reverse transcriptase) activator that enhances TERT transcriptional activity through the MEK/ERK/AP-1 cascade pathway, promotes telomere synthesis in primary human cells and naturally aged mice, reduces cellular senescence and inflammatory cytokines, and alleviates neuroinflammation, among other effects.

HDB-1 blocks the activation of hepatic stellate cells (HSC) by inhibiting the PKA/Raf1/MEK/ERK signaling pathway mediated by P2Y14R, thereby alleviating the core pathological process of liver fibrosis. HDB-1 is used in liver fibrosis research models to investigate purinergic receptor signaling specificity, hepatic stellate cell activation pathways, and downstream MAPK pathway modulation in fibrogenesis-related cellular systems.

The Survival of Motor Neurons (SMN) protein participates in RNA splicing. Decreases in SMN, typically a consequence of defects in the smn1 gene, result in the death of motor neurons and lead to the neurodegenerative disease, spinal muscular atrophy (SMA). Cuspin-1 is a small molecule upregulator of SMN that has been shown in vitro to increase levels of SMN in SMA patient fibroblasts by 50% at 18 μM. Its mechanism of action is thought to involve increased phosphorylation of ERK to initiate Ras-Raf-MEK signaling, which results in an increased rate of SMN translation.

iMDK quarterhydrate, a potent PI3K inhibitor, is effective in inhibiting the growth factor MDK (also known as midkine or MK) while demonstrating suppression of non-small cell lung cancer (NSCLC). In combination with a MEK inhibitor, iMDK quarterhydrate demonstrates cooperative inhibition of NSCLC without causing harm to normal cells and mice [1].
