1. A method for treating a pathological condition or symptom in a subject, wherein the activity of A 2A adenosine receptors is implicated and agonism of such activity is desired, comprising administering to the subject an effective amount of a compound of formula Ia or a pharmaceutically acceptable salt thereof:

R 1 and R 2 independently are selected from the group consisting of H, (C 1 -C 8 )alky, (C 3 -C 8 )cycloalkyl, (C 3 -C 8 )cycloalkyl(C 1 -C 8 )alkylene, aryl, aryl(C 1 -C 8 )alkylene, heteroaryl, heteroaryl(C 1 -C 8 )alkylene-, diaryl(C 1 -C 8 )alkylene, and diheteroaryl(C 1 -C 8 )alkylene, wherein the aryl and heteroaryl rings are optionally substituted with 1-4 groups independently selected from fluoro, chloro, iodo, bromo, methyl, trifluoromethyl, and methoxy;

each R independently is selected from the group consisting of H, C 1 -C 4 alkyl, cyclopropyl, cyclobutyl, and (CH 2 ) a cyclopropyl;

X is CH or N, provided that when X is CH then Z cannot be substituted with halogen, C 1 -C 6 alkyl, hydroxyl, amino, or mono- or di-(C 1 -C 6 -alkyl)amino;

Y is selected from the group consisting of O, NR 1 ,—(OCH 2 CH 2 O) m CH 2 —, and —(NR 1 CH 2 CH 2 O) m CH 2 —, provided that when Y is O or NR 1 , then at least one substituent is present on Z;

Z is selected from the group consisting of 5-membered heteroaryl, 6-membered aryl, 6-membered heteroaryl, carbocyclic biaryl, and heterocyclic biaryl, wherein the point of attachment of Y to Z is a carbon atom on Z, wherein Z is substituted with 0-4 groups independently selected from the group consisting of F, Cl, Br, I, (C 1 -C 4 )alkyl, —(CH 2 ) a OR 3 , —(CH 2 ) a NR 3 R 3 ,—NHOH, —NR 3 NR 3 , nitro, —(CH 2 ) a CN, —(CH 2 ) a CO 2 R 3 , —(CH 2 ) a CONR 3 R 3 ,trifluoromethyl, and trifluoromethoxy;

alternatively, Y and Z together form an indolyl, indolinyl, isoindolinyl, tetrahydroisoquinolinyl, or tetrahydroquinolinyl moiety wherein the point of attachment is via the ring nitrogen and wherein said indolyl, indolinyl, isoindolinyl, tetrahydroisoquinolinyl, or tetrahydroquinolinyl moiety, which is substituted with 0-4 groups independently selected from the group consisting of F, Cl, Br, I, C 1 -C 4 alkyl, —(CH 2 ) a OR 3 , —(CH 2 ) a NR 3 R 3 , —NHOH, —NR 3 NR 3 R 3 , NO 2 , —(CH 2 ) a CN, —(CH 2 ) a CO 2 R 3 , —(Ch 2 ) a CONR 3 R 3 , CF 3 , and OCF 3 ;

R 3 is independently selected from the group consisting of H, (C 1 -C 6 )alkyl, cycloalkyl, aryl, and heteroaryl;

R 4 is selected from the group consisting of CH 2 OR, C(O)NRR, and CO 2 R;

a is selected from 0, 1, and 2;

m is selected from 1, 2, and 3;

n is selected from 0, 1, and 2;

each p independently is selected from 0, 1, and 2; and,

q is selected from 0, 1, and 2.

2. The method of claim 1 , wherein the pathological condition or symptom is caused by autoimmune stimulation (autoimmune diseases), inflammation, allergic diseases, skin diseases, infectious diseases, wasting diseases, organ transplantation, tissue or cell transplantation, open wounds, adverse effects from drug therapy, a cardiovascular condition, ischemia-reperfusion injury, dialysis, gout, chemical trauma, thermal trauma, diabetic nephropathy, sickle cell disease, laminitis, and founder's disease.

3. A method to diagnose myocardial perfusion abnormalities in a mammal comprising: (a) parenterally administering to said mammal an amount of a compound of formula Ia or a pharmaceutically acceptable salt thereof: and (b) performing a technique on said mammal to detect the presence of coronary artery stenoses, assess the severity of coronary artery stenoses or both

each R independently is selected from the group consisting of H, C 1 -C 4 alkyl, cyclopropyl, cyclobutyl, and (CH 2 ) a cyclopropyl;

X is CH or N, provided that when X is CH then Z cannot be substituted with halogen, C 1 -C 6 alkyl, hydroxyl, amino, or mono- or di-(C 1 -C 6 -alkyl)amino;

Z is selected from the group consisting of 5-membered heteroaryl, 6-membered aryl, 6-membered heteroaryl, carbocyclic biaryl, and heterocyclic biaryl, wherein the point of attachment of Y to Z is a carbon atom on Z, wherein Z is substituted with 0-4 groups independently selected from the group consisting of F, Cl, Br, I, (C 1 -C 4 )alkyl, —(CH 2 ) a OR 3 , —(CH 2 ) a NR 3 R 3 , —NHOH, —NR 3 NR 3 R 3 , nitro, —(CH 2 ) a CN, —(CH 2 ) a CO 2 R 3 , —(CH 2 ) a CONR 3 R 3 ,trifluoromethyl, and trifluoromethoxy;

R 3 is independently selected from the group consisting of H, (C 1 -C 6 )alkyl, cycloalkyl, aryl, and heteroaryl;
