Dopamine is an important neurotransmitter in the human brain and its altered concentrations can lead to various neurological diseases. We studied the binding of novel compounds at the dopamine D2 (D2R) and D3 (D3/sub

We recently reported molecules designed according to the multitarget-directed ligand paradigm to exert combined activity at human fatty acid amide hydrolase (FAAH) and dopamine receptor subtype D3 (D3R). Both targets are relevant for tackling several types of addiction (most notably nicotine addiction) and other compulsive behaviors. Here, we report an SAR exploration of a series of biphenyl-N-[4-[4-(2,3-substituted-phenyl)piperazine-1-yl]alkyl]carbamates, a novel class of molecules that had shown promising activities at the FAAH-D3R target combination in preliminary studies. We have rationalized the structural features conducive to activities at the main targets and investigated activities at two off-targets: dopamine receptor subtype D2 and endocannabinoid receptor CB1. To understand the unexpected affinity for the CB1 receptor, we devised a 3D-QSAR model, which we then prospectively validated. Compound 33 was selected for PK studies because it displayed balanced affinities for the main targets and clear selectivity over the two off-targets. 33 has good stability and oral bioavailability and can cross the blood-brain barrier.

Two series of novel quinazolin-4(3H)-one derivatives (10a–g and 11a–g) have been synthesized and evaluated for their in vitro antiproliferative activity against human HeLa, MIAPACA, MDA-MB-231, and IMR-31 cancer cell lines. The synthesized compounds were characterized by spectral (Fourier transform infrared, 1H nuclear magnetic resonance, 13C nuclear magnetic resonance, high-resolution mass spectra) methods. Among them, compounds 11e and 11g exhibited potent in vitro antiproliferative activity with GI50 values 0.02, less than 0.01 μM against MIAPACA human cancer cell line. Significantly, compounds 10a, 10b, 10c, 10g, 11b, 11c, 11d, 11e, 11f showed activity with GI50 values ranging from 0.1 to 0.87 μM against human cancer cell lines MIAPACA, MDA-MB-231, and IMR-31. We have explored the probable binding mode and key active site interactions in HDAC8 and EHMT2 proteins. The docking results are complementary to the experimental results.
