In p53 wild-type NB cells, NSC-697923 promotes the nuclear importation of p53, thereby triggering cell death. Meanwhile, in p53 mutant NB cells, NSC-697923 activates the JNK-mediated apoptotic pathway, leading to cell death. Additionally, NSC-697923 inhibits DNA damage and NF-κB signaling, further contributing to its antitumor activity.

Olomoucine also inhibits replication of herpes simplex virus 1 (HSV-1), HSV-2, vaccinia virus, human adenovirus type 4 (Ad4), and human CMV (IC50s = 5, 4.7, 3.8, 2.4, and 3.2 μM, respectively) but not measles virus or influenza virus (IC50s = >20 μM for both).3

CC260, a selective inhibitor for PI5P4Kα and PI5P4Kβ with Kis of 40 nM and 30 nM respectively, exhibits minimal to no inhibition against other protein kinases like Plk1 and RSK2. It is applicable in the research of cell energy metabolism, diabetes, and cancer[1].

The protein p53, often called the 'guardian of the genome,' is a transcription factor that is activated in response to cellular stress (low oxygen levels, heat shock, DNA damage, etc.) and acts to prevent further proliferation of the stressed cell by promoting cell cycle arrest or apoptosis. Its role as a tumor suppressor is evident by the observation that approximately 50% of human tumors have mutated or non-functional p53. PK7242 is an inducer of reactivation of mutant p53 in cancer cells. In cancer cells carrying the Y220C mutant, PK7242 binds to the p53-Y220C core domain and induces growth inhibition, cell-cycle arrest, and apoptosis.
