Synthesis and phosphodiesterase 5 inhibitory activity of novel phenyl ring modified sildenafil analogues

, p. 1609 - 1616 (2007/10/03)

New sildenafil analogues containing an ether ring fused into the phenyl moiety, 6a-d and 7a-d, were efficiently synthesized from the readily available starting materials, 1a-d and 2, in five steps. Ab initio calculations indicated that introduction of a cyclic ether to the phenyl group might enhance the co-planarity of the molecule. The torsional angles were calculated to be 2-3° for the 5-membered cyclic ether derivatives, 6a, 6c, 7a, and 7c, and 12-16° for the 6-membered ones, 6b, 6d, 7b, and 7d. On the other hand, sildenafil showed the least co-planarity with the torsional angle of 23° compared with the target compounds, 6a-d and 7a-d. in the enzyme assay, however, the in vitro PDE 5 inhibitory activity was found out to be inversely related to the degree of co-planarity. In other words, the least planar sildenafil showed the highest actiivty, and the most planar 5-membered cyclic ether derivatives were least active by 100-200-fold compared with sildenafil. Our study clearly demonstrated that the open chain 2'-alkoxy group of the phenyl ring, although less effective for inducing the co-planarity, seemed to act as a much better lipophilic requirement than the cyclic alkoxy moiety.

Synthesis and properties of Biagra [1]. A 5-(2,3-dihydro-7-benzofuryl) analog of Viagra

Voelter, Wolfgang,El-Abadelah, Mustafa M.,Sabri, Salim S.,Khanfar, Monther A.

, p. 1469 - 1473 (2007/10/03)

The synthesis and spectral properties (IR, MS, NMR) of a substituted 5-(2,3-dihydro-7-benzofuryl)pyrazolo[4,3-d]pyrimidin-7-one (2), an analog of Viagra (1), are described. The generally applicable route involves interaction of 2,3-dihydro-7-benzofuranoyl chloride (3) with 4-amino-1-methyl-3-propyl-5-pyrazolecarboxamide (4), and the resulting bis-amide (5) is cyclized to the corresponding substituted pyrazolo[4,3-d]pyrimidin-7-one (6). Chlorosulfonylation of 6, followed by treatment with 1-methylpiperazine, furnished the title compound 2 (named Biagra). Preliminary experiments "associated with the erectile process" on rats lend evidence of greater potency of Biagra (2) as compared to Viagra (1).

Synthesis of new 7-benzofuranmethanamines as heterocyclic analogues of the squalenepoxidase-inhibitor Butenafine

Stanetty,Koller,Purstinger,Grubner

, p. 351 - 358 (2007/10/02)

Selected title compounds (6a-f, 7a-d) were synthesized by RedAl(R)-reduction of the carboxamides 4a-f and 5a-d, easily available from the corresponding (2,3-dihydro-)7-benzofurancarboxylic acids 1a-f or 2a-d, respectively. For practical reasons, the preparation of the 2,3-dihydro-2-methyl-7-benzofuranmethanamines 6h-k with varied N-substitution by alkylation of the N-methyl-benzofuranmethanamine 6g with preformed aralkylbromides 9a-d was preferred.
