and α1 adrenergic receptors. Compound 50 showed 3-fold higher in vitro stability towards oxidative metabolism than 1 and was able to stimulate neurite outgrowth in neuronal primary cultures through the 5-HT7 receptor in a shorter time and at a lower concentration than the agonist 1. A preliminary disposition study in mice revealed that compound 50 was metabolically stable and was able to pass the blood–brain
A series of novel 4, 5-dihydro-5-methyl-6-(2 or 4-substituted 7-quinazolinyl)-3(2H)-pyridazinones was synthesized and examined for cardiotonic activity in anesthetized dogs. The 4-substituted aminoquinazolines generally showed potent and long-lasting inotropic activity. Fall in the activity was observed on the introduction of substituent at the 2-position of the quinazoline ring. The 3-substituted 4 (3H)-quinazolinimines generally exhibited weak activity. Ca+2 sensitizing effect of the 4-substituted amino derivatives was also examined in chemically skinned fiber from papillary muscle of guinea pig. The alkylamino derivatives exhibited small sensitizing effect, while the benzylamino derivatives exhibited large effect. Among them, KF15232 (Ix) was found to have the most potent cardiotonic and Ca2+ sensitizing activities.

Ammonium chloride promotes the selective formation of monosubstituted ureas undermicrowaveirradiation. Most nucleophiles, acid-labile functionalities, and protecting groups are well tolerated in this reaction. By avoiding transition metals and mineral acids, this methodology offers a more sustainable alternative for the synthesis of monosubstituted ureas and their analogs.
A heterocyclic compound represented by the general formula (in the formula, R1, R2 and R3 may be the same or different, and each represents a hydrogen atom, a halogen atom, or this general formula (X1-Y1-R4) (in the formula: X1 represents this general formula (NR5) (in the formula, R5 represents a hydrogen atom, etc.) or the like; Y1 represents an optionally substituted C1-6 alkylene group or the like; and R4 represents an optionally substituted aryl group or the like), and Z represents a nitrogen atom or this general formula (CR6) (in the formula, R6 represents a hydrogen atom, a halogen atom, or an optionally substituted C1-12 alkyl group or the like)), or a salt thereof, exhibits excellent anti-HIV activity and is useful as an anti-HIV agent.

The design and synthesis of molecules containing both a substrate-binding cavity and a nearby catalytically active metal center is a useful approach to the development of synthetic systems that function according to the principles of enzymes. To this end the receptor molecule 2a, derivedfromdiphenylglycoluril, was functionalized with triaryl phosphite ligands to give the receptor ligand 2d. Exchange
