VLX 1500 is a potent deubiquitinating enzyme (DUBs) inhibitor designed to overcome resistance to traditional proteasome inhibitors. It triggers ER stress-mediated apoptosis by specifically blocking USP14/UCHL5 activity on the 19S regulatory particle, leading to a lethal accumulation of ubiquitinated proteins, widely used in drug target screening for relapsed hematological malignancies.

Toladryl is a derivative of Diphenhydramine that can cross the blood-brain barrier and exhibits oral activity, with antihistamine and anticholinergic properties. Its anticholinergic effects are approximately a tenth of those seen with Diphenhydramine, yet it offers 2-4 times the protection against lethal doses of histamine in guinea pigs. The side effects of Toladryl are fewer and milder compared to Diphenhydramine; however, at higher doses, it may cause symptoms such as insomnia, agitation, and disorientation related to the central nervous system. Toladryl is utilized in the research of allergic diseases.

Compound 7l, an acaricide, serves as an effective LSD1 inhibitor. It demonstrates substantial acaricidal activity against the eggs of T. cinnabarinus, with a lethal concentration 50 (LC50) of 0.0035 mg/L.

PF-477736, also known as PF-00477736, is a potent CHK1 inhibitor with potential to enhance chemotherapy. This compound inhibits CHK1, an ATP-dependent serine/threonine kinase that is a crucial component of the S/G2 checkpoint system for DNA replication monitoring. By bypassing the final checkpoint defenses against DNA damage-induced lethal effects, PF-477736 may improve the antitumor efficacy of various chemotherapeutic agents in tumor cells with inherent checkpoint deficiencies.
