Since it is widely distributed into the body, β3-adrenoceptor is becoming an attractive target for the treatment of several pathologies such as obesity, type 2 diabetes, metabolic syndrome, cachexia, overactive bladder, ulcero-inflammatory disorder of the gut, preterm labour, anxiety and depressive disorders, and heart failure. New compounds belonging to the class of arylethanolamines bearing one or two stereogenic centres were prepared in good yields as racemates and optically active forms. They were, then, evaluated for their intrinsic activity towards β3-adrenoceptor and their affinity for β1- and β2-adrenergic receptors. Stereochemical features were found to play a crucial role in determining the behaviour of such compounds. In particular, α-racemic, (αR)- and (αS)-2-{4-[2-(2-hydroxy-2-phenylethylamino)ethyl]phenoxy}-2- methylpropanoic acid, (α-rac, β-rac)-, (αR, βS)- and (αR, βR)- 2-{4-[2-(2-hydroxy-2-phenylethylamino)ethyl]phenoxy}propanoic acid were found to be endowed with β3-adrenoceptor agonistic activity. Whereas, (αS, βS)- and (αS, βR)-2-{4-[2-(2-hydroxy-2-phenylethylamino)ethyl]phenoxy}propanoic acid behaved as β3-adrenoceptor inverse agonists. Such compounds showed no affinity for β1- and β2-adrenergic receptor, respectively. Thus, resulting highly selective β3-adrenoceptor ligands.

Design and synthesis of a novel potent glycoprotein IIb-IIIa (GP IIb-IIIa) receptor antagonist based on isoindolone skeleton has been described. This scaffold has been derived from earlier reported pseudopeptides. Synthesis by a novel route has been achieved. Few molecules show very potent in vitro activity. Further identification of probable additional hydrogen bond donor site has been described.
Beta(3)-adrenoceptor agonists for the treatment of frequent urination and urinary incontinence: 2-[4-(2-[[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino]ethyl)phenoxy]-2-methylpropionic acid.

In a search for novel analogues of beta(3)-adrenoceptor (AR) agonists relaxing the bladder for treatment of urinary dysfunction, 2-[4-(2-[[(1S,2R)-2-hydroxy-2-(4-hydroxyphenyl)-1-methylethyl]amino]ethyl)phenoxy]-2-methylpropionic acids (1a-e), into which a fibrate-like structure had been incorporated, were synthesised. Compound 1a was found to be a selective beta(3)-AR agonist in functional assays using the ferret detrusor (beta(3)-AR), rat uterus (beta(2)-AR), and rat atrium (beta(1)-AR); beta(3): EC(50)=7.8 nM, beta(2): IC(50)=7,300 nM, beta(1): EC(20)=23,000 nM. The introduction of a chlorine atom or methyl substituent at the ortho-position on the phenyl ring of 1a further improved beta(3)-AR selectivity. In an in vivo study, 1a lowered intrabladder pressure (ED(50)=31 microg/kg) in rats, without increasing heart rate, in keeping with the in vitro results. Consequently, it is proposed that 1a and its analogues (1b-e), possess beta(3)-AR agonistic activity in the absence of undesirable beta(1)- or beta(2)-AR mediated actions, and may be useful for clinical treatment and pharmacological studies.

The invention concerns α-aminoacyl derivatives of phenyl-, phenoxy-, thiophenoxy- and phenylsulphinylalkanoic acids together with their amides, esters and pharmaceutically acceptable salts; processes for their preparation; and pharmaceutical compositions for therapeutic use in inhibiting the formation of thrombi and also in reducing the persistence of thrombi formed in the blood of warm blooded animals. Representative compounds of the invention are methyl 4-(aminoacetyl)phenoxyacetate, 4-(aminoacetyl)phenoxyacetic acid and methyl 4-(aminoacetyl)-thiophenoxyacetate, preferably as their hydrochlorides.
