Optimization of Activity, Selectivity, and Liability Profiles in 5-Oxopyrrolopyridine DPP4 Inhibitors Leading to Clinical Candidate (Sa)-2-(3-(Aminomethyl)-4-(2,4-dichlorophenyl)-2-methyl-5-oxo-5H-pyrrolo[3,4-b]pyridin-6(7H)-yl)-N,N-dimethylacetamide (BMS-767778)
摘要:
Optimization of a 5-oxopyrrolopyridine series based upon structure activity relationships (SARs) developed from our previous efforts on a number of related bicyclic series yielded compound 2s (BMS-767778) with an overall activity, selectivity, efficacy, PK, and developability profile suitable for progression into the clinic. SAR in the series and characterization of 2s are described.

A novel class of 2-(4-heterocyclylphenyl)-1,4-dihydropyridines (2-38) possessing antagonist activity against platelet activating factor (PAF) was prepared by the Hantzsch synthesis from a variety of ethyl 4'-heterocyclic-substituted benzoylacetates, aryl or heteroaryl aldehydes, and substituted 3-aminocrotonamides or 3-aminocrotonate esters. Structure-activityrelationships were evaluated where PAF

We report the synthesis and evaluation of novel alpha(1a) adrenoceptor subtype-selective antagonists. Systematic modification of the lipophilic 4,4-diphenylpiperidinyl moiety of the dihydropyridine derivatives 1 and 2 provided several highly selective and potent alpha(1a), antagonists. From this series, we identified the 4-(methoxycarbonyl)-4-phenylpiperidine analogue SNAP 5540 (-) [(-)-63] for further characterization. When examined in an isolated human prostate tissue assay, this compound was found to have a K-i of 2.8 nM, in agreement with the cloned human receptor binding data (K-i = 2.42 nM). Further evaluation of the compound in isolated dog prostate tissue showed a K-i of 3.6 nM and confirmed it to be a potent antagonist (K-b = 1.6 nM). In vivo, this compound effectively blocked the phenylephrine-stimulated increase in intraurethral pressure (IUP) in mongrel dogs, at doses which did not significantly affect the arterial pressure (diastolic blood pressure, DBP), with a DBP K-b/IUP K-b ratio of 16. In addition, (-)-63 also showed greater than 40 000-fold selectivity over the rat L-type calcium channel and 200-fold selectivity over several G protein-coupled receptors, including histamine and serotonin subtypes. These findings prove that alpha(1a) adrenoceptor-subtype selective antagonists such as (-)-63 may be developed as uroselective agents for an improved treatment of BPH over nonselective alpha(1) antagonists such as prazosin and terazosin, with fewer side effects.

An approach to designing dihydropyridines that bind to adenosine receptors without binding to L-type calcium channels has been described. 1,4-Dihydropyridine derivatives substituted with beta-styryl or phenylethynyl groups at the 4-position and aryl groups at the 6-position were synthesized and found to be selective for human A(3) receptors. Combinations of methyl, ethyl, and benzyl esters were included at the 3- and 5-positions. Affinity was determined in radioligand binding assays at rat brain A(1) and A(2A) receptors using [H-3]-(R)-PIA [[H-3]-(R)-N-6-(phenylisopropyl)adenosine] and [H-3]CGS 21680 [[H-3]-2-[[4-(2-carboxymethyl)phenyl]ethylamino]-5'-(N-ethyl carbamoyl)adenosine], respectively. Affinity was determined at cloned human and rat A(3) receptors using [I-125]AB-MECA [N-6-(4-amino-3-iodobenzyl)-5'-(N-methycarbonyl)adenosine]. Structure-activity analysis indicated that substitution of the phenyl ring of the beta-styryl group but not of the 6-phenyl substituent was tolerated in A(3) receptor selective agents. Replacement of the 6-phenyl ring with a 3-thienyl or 3-furyl group reduced the affinity at A(3) receptors by 4- and g-fold, respectively. A 5-benzyl ester 4-trans-beta-styryl derivative, 26, with a K-i value of 58.3 nM at A(3) receptors, was >1700-fold selective vs either A(1) receptors or A(2A) receptors. Shifting the benzyl ester to the 3-position lowered the affinity at A(3) receptors 3-fold. A 5-benzyl, 3-ethyl ester 4-phenylethynyl derivative, 28, displayed a K-i value of 31.4 nM at A(3) receptors and 1300-fold selectivity vs A(1) receptors. The isomeric 3-benzyl, 5-ethyl diester was >600-fold selective for A(3) receptors. Oxidation of 28 to the corresponding pyridine derivative reduced affinity at A(3) receptors by 88-fold and slightly increased affinity at A(1) receptors.
