Pyrimidinone, oxazolidinone, and (alkyl)aryl derivatives, their synthesis, and their use as alpha 1a adrenergic receptor antagonists are disclosed. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia are achieved. Among the disclosed derivatives are piperidinyl aminoalkylpiperidinyl pyrimidinones, including those of formula:
R1 is selected from unsubstituted, mono- or poly-substituted phenyl wherein the substituents on the phenyl are independently selected from halogen, CF3, cyano, nitro, N(R7)2, NR7COR19, NR7CON(R19)2, NR7SO2R19, NR7SO2N(R19)2, OR6, (CH2)0-4CO2R7, (CH2)0-4CON(R7)2, or C1-4 alkyl; or unsubstituted, mono- or poly-substituted pyridyl, pyrazinyl, thienyl, thiazolyl, furanyl, quinazolinyl or naphthyl wherein the substituents on the pyridyl, pyrazinyl, thienyl, thiazolyl, furanyl, quinazolinyl or naphthyl are independently selected from CF3, cyano, nitro, amino, (CH2)0-4CO2R7, (CH2)0-4CON(R7)2, (CH2)0-4SO2N(R7)2, (CH2)0-4SO2R6, phenyl, OR6, halogen, C1-4 alkyl or C3-8 cycloalkyl;
m and p are each integers from zero to two, wherein the sum m+p=2; n and o are each integers from zero to two, wherein the sum n+o=2; q is an integer of from zero to three, provided that when q is zero, R26 is hydrogen; s is an integer of from zero to four; and
E, G, J, L, M, W, X, R2, R3, R4, R5, R6, R7, R8, R11, R12, R13, R14, R15, R16, R19 and R26 are defined herein.
揭示了吡啶酮,噁唑烷酮和(烷基)芳基衍生物,它们的合成以及它们作为α1a肾上腺素受体拮抗剂的用途。这些化合物的一个应用是治疗良性前列腺增生。这些化合物在选择性上能够放松富含α1a受体亚型的平滑肌组织,同时不会引起低血压。这样的组织之一是发现在尿道内壁周围。因此,这些化合物的一个用途是为患有良性前列腺增生的男性提供急性缓解,从而减少尿液流动的阻碍。这些化合物的另一个用途是与人类5-α还原酶抑制剂化合物结合,以实现对良性前列腺增生影响的急性和慢性缓解。在所披露的衍生物中,包括哌啶基氨基烷基哌啶基吡啶酮,其化学式为:R1选择自未取代,单取代或多取代苯基,其中苯基上的取代基独立选择自卤素,CF3,氰基,硝基,N(R7)2,NR7COR19,NR7CON(R19)2,NR7SO2R19,NR7SO2N(R19)2,OR6,(CH2)0-4CO2R7,(CH2)0-4CON(R7)2,或C1-4烷基;或未取代,单取代或多取代吡啶基,吡嗪基,噻吩基,噻唑基,呋喃基,喹唑啉基或萘基,其中吡啶基,吡嗪基,噻吩基,噻唑基,呋喃基,喹唑啉基或萘基上的取代基独立选择自CF3,氰基,硝基,氨基,(CH2)0-4CO2R7,(CH2)0-4CON(R7)2,(CH2)0-4SO2N(R7)2,(CH2)0-4SO2R6,苯基,OR6,卤素,C1-4烷基或C3-8环烷基;m和p分别是从零到两的整数,其中m+p=2;n和o分别是从零到两的整数,其中n+o=2;q是从零到三的整数,条件是当q为零时,R26为氢;s是从零到四的整数;以及E、G、J、L、M、W、X、R2、R3、R4、R5、R6、R7、R8、R11、R12、R13、R14、R15、R16、R19和R26在此处定义。
