Four amidato divalent lanthanide complexes, {LnLn[N(TMS)2]THF}2 [n = 1, Ln = Eu (1); n = 2, Ln = Eu (3), Yb (4); HL1 = tBuC6H4CONHC6H3(iPr)2; HL2 = C6H5CONHC6H3(iPr)2] and {L3Eu[N(TMS)2]THF}{L32Eu(THF)2} (2) [HL3 = ClC6H4CONHC6H3(iPr)2], were synthesized and extensively characterized. This is the first time that the amidato lanthanide amides 1-4 were used to catalyze the reactions of CO2 and 2-aminobenzonitriles to form quinazoline-2,4(1H,3H)-diones at atmospheric pressure. All the complexes efficiently catalyzed the transformation, with complex 3 showing the highest activity. This catalytic system gave good to excellent yields, and good functional group tolerance. Preliminary studies were conducted to investigate the reaction mechanism.

Hit optimization of the class of quinazoline containing histamine H 4 receptor (H4R) ligands resulted in a sulfonamide substituted analogue with high affinity for the H4R. This moiety leads to improved physicochemical properties and is believed to probe a distinct H4R binding pocket that was previously identified using pharmacophore modeling. By introducing a variety of sulfonamide substituents, the H4R affinity was optimized. The interaction of the new ligands, in combination with a set of previously published quinazoline compounds, was described by a QSAR equation. Pharmacological studies revealed that the sulfonamide analogues have excellent H4R affinity and behave as inverse agonists at the human H4R. In vivo evaluation of the potent 2-(6-chloro-2-(4-methylpiperazin-1-yl)quinazoline4-amino)-N- phenylethanesulfonamide (54) (pki = 8.31 ± 0.10) revealed it to have anti-inflammatory activity in an animal model of acute inflammation.
