DESCRIPTION
Technical Field
This invention relates to novel amide derivatives and salts thereof which are useful as a ROCK inhibitor.
Background Art
Rho kinases (ROCK) are serine/threonine kinases that function in downstream of Rho which is a low molecular GTP-binding protein, and two ROCK isoforms, ROCK I and ROCK II, have been identified. The enzymes are involved in a variety of biological events such as cytoskeltal control, cell growth, cell migration, apoptosis, inflammation etc. To date, it has been reported that the enzymes are involved in pathology of circulatory system disease, tumor infiltration, osteogenesis etc (see, e.g., Satoh H. et al, Jpn. J. Pharmacol, 79, Suppl I, 211 (1999), Kuwahara K. etal, FEES Lett 452, 314-318 (1999), SawadaN. etal. Circulation 101, 2030-2033 (2000) , Kataoka C. et al. Hypertension. 2002 Feb; 39(2): 245-50, Imamura F. et al, Jpn. J. Cancer Res. 200; 91: 811-16, Itoh K. et al, Nat. Med. 1999; 5: 221-5, Nakajima M. et al, Clin. exp. Pharmacol. Physiol. 2003 Jul; 30(7): 457-63), and recently the involvement of the enzymes in chondrocyte differentiation and neurogenic pains etc has been investigated (see, e.g., Guoyan W. et al, J. Biol. Chem. 2004; 279(13), 13205-13214, Tatsumi S, Neuroscience. 2005; 131(2): 491-498). With elucidation of such many functions of ROCK in the body, many compounds which can inhibit the functions of the enzymes (ROCK inhibitors) has been studied extensively (see, e*g., WO98/06433, WOOO/09162, WOOO/7 8351, WOOl/175 62, WO02/07 697 6, EP125 6574, WO02/100833, WO03/082808, WO2004/009555, WO2004/02 4717, WO2004/108724, WO2005/003101, WO2005/035501, WO2005/035503, WO2005/035506, W02005/058891, WO2005/074 642, WO2005/07 4 64 3, WO2005/080 934, W02005/082367, WO2005/0828 90, WO2005/0977 90, WO2005/100342, WO2005/103050, WO2005/105780, WO2005/108397,

2. Assessment of changes in hindlimb weight distribution by ROCK inhibitor
As intra-articular injection of monosodium iodoacetate(MIA) induced human osteoarthritis-like histopathological changes in knee joint, this model would be very useful for the study of human osteoarthritis. Recently, it is reported the clinical scores of the joint pain were closely correrated to the grade of histological findings (J Vet Med Sci 65,1195,2003)and this model may be useful for estimation of therapeutic effects of pain with osteoarthritis,
Male SD rats were anesthetized with halothane(Takeda, Japan) and given single intra-articular injection of Img of monosodium iodoacetate(MIA; Sigma, St.Louis, USA) through the infrapatellar ligament of the right knee. MIA was dissolved with physiologic saline and administered in a volume of 50 ul using a 27-gauge, 0.5-inch needle. Three weeks after the injection, hindlimb weight distribution was determined using an

incapacitancetester (Linton Instrumentation^ Norfork, UK) . Rats were allowed to acclimate to the testing apparatus and when stationary, readings were taken over a 5s period. Oral administration of chemical compounds restored the difference in the amount of weight between the left and right limbs. Each group in each experiment were performed in about 8 animals.

3 . Pain alleviation effect of ROCK inhibitor onbradykinin induced joint pain model
Bradykinin is known to be one of the important pain-related mediators in various pain and especially, sodium hyaluronate which is useful for pain in osteoarthritis is reported to be effective in bradykinin-induced joint pain model. Therefore, we examined effects of compounds in the model.
The making of the joint pain model and evaluation of a level of pain was conducted essentially based on the method described in Folia Pharmacol, japon., 92, 17-27 (1988) . Female SD rats (6-7 weeks old, Charles River Japan, Inc.) were anesthetized with halothane (Wako). Compound of the above Example were administrated orally to the rat by using oral sonde for rat. 60 min after administration of the compound, saline solution of bradykinin was injected into knee joint cavity of hind limb of rat (3 uM/site/50 ul), and then the response to pain of the rat after administration of bradykinin was observed. Level of pain was scored as five grade point (0-4) as follow: 0: no lameness

to lameness for 10 seconds; 1: lameness for 10 to 30 seconds; 2: lift of the limb within 10 seconds or lameness for 31 or more seconds; 3: three-legged gait within 10 seconds followed by lameness; 4: three-legged gait for 10 or more seconds followed by lameness. About 10 rat models were used in each experimental group. It was confirmed that administration of bradykinin leads to response to pain scored as about 3- Administration of the compound of the present invention at 32 mg/kg significantly improved the response to pain of the rat models. The compound of Example 26 dose dependently improved bradykinin-induced pain responses, especially, the pain score significantly reduced from 2.7 in vehicle to 1.4 at the dose of 32 mg/kg.
4. Assessment of changes in cartilage surface lesion by ROCK
inhibitor
As intra-articular injection of monosodium iodoacetate (MIA) induced human osteoarthritis-like histopathological changes in knee joint, this model would be very useful for the study of human osteoarthritis.To evaluate the usefulness of the compounds to joint cartilage damage in osteoarthritis, we examined effects of the compounds on cartilage damage in the model.
Male SD rats were anesthetized with halothane(Takeda, Japan) and given single intra-articular injection of Img of monosodium iodoacetate(MIA; Sigma, St.Louis, USA) through the infrapatellar ligament of the right knee. MIA was dissolved with physiologic saline and administered in a volume of 50 ul using a 27-gauge, 0.5-inch needle. Three weeks after the injection, a right tibia was isolated and the lesion of the tibial surface were assessed on a scale of 0-4. Each group in each experiment were performed in about 8 animals. The severity of macroscopic cartilage lesion was observed with score of about 3 three weeks after injection of MIA. Articular injection of the compounds twice a week inhibited cartilage damage*
5. Assessment of effects on hindlimb blood flow by ROCK inhibitor
As one of the study to clarify the usefulness of the compounds

of the present invention for peripheral arterial disease, we conducted a study to evaluate the effects of the compounds on hindlimb blood flow in rats.
Male Wistar rats were anesthetized by intraperitoneal pentobarbitalinjection (Kanto chemical, Japan) after oral administration of compounds. Rats were placed on a heating plate for subsequent hindlimb blood flow analysis . We measured hindlimb blood flow using a laser Doppler blood flowmeter (Peri Scan System, Stockholm, Sweden) , After the laser Doppler images were recorded, the average perfusion values of both limbs were calculated, and evaluated the effects of compounds on hindlimb blood flow. Each experiment was performed in about 4 animals.

6. Assessment of the inhibitory effects on phenylephrine-induced elevation of urethral pressure by ROCK inhibitor
To evaluate the usefulness of the compounds of the present invention for urinary dysfunction associated with benign prostatic hyperplasia, we investigated the inhibitory effects of the intravenous administration of the compounds on phenylephrine-induced elevation of the urethral pressure in rats .
Male Wistar rats were anesthetized with urethane(SIGMA, USA) . After midline abdominal incision, catheter to measure the urethral pressure (3.5 Fr, Millar, USA) was inserted into the urethra from top of the bladder. After confirming the Phenylephrine (30 ug/kg i, v.) -induced elevation of the urethral pressure, compounds were administered intravenously in

increasing doses. Every 5 min after administration of compounds, Phenylephrine (30 ug/kg i,v.) was injected, and the inhibitory effects of compounds on phenylephrine-induced elevation of urethral pressure were evaluated. Each experiment was performed in about 4 animals.
