A series of dialkyl, dicycloalkyl, and diaryl ester analogues of nifedipine, in which the ortho-nitro phenyl group at position 4 is replaced by the 4-(5)-chloro-2-ethyl-5-(4)-imidazolyl substituent, were synthesized and evaluated as calcium channel antago

A new series of non-nucleoside reverse transcriptase inhibitors based on an imidazole-amide biarylether scaffold has been identified and shown to possess potent antiviral activity against HIV-1, including the NNRTI-resistant Y188L mutated virus. X-ray crystallography of inhibitors bound to reverse transcriptase, including a structure of the Y188L RT protein, was used extensively to help identify and optimize the key hydrogen-bonding motif. This led directly to the design of compound 43 that exhibits remarkable antiviral activity (EC50 1 nM) against a wide range of NNRTI-resistant viruses and a favorable pharmacokinetic profile across multiple species.

, (2008/06/13)
A process for preparing, on an industrial scale, 4-halo-5-(hydroxymethyl) imidazole compounds that are useful as intermediates for medicines. A 4-chloro-5-(hydroxymethyl) imidazole compound, a 4-bromo-5-(hydroxymethyl) imidazole compound or a like compound is synthesized by reacting a 4,5-bis(hydroxymethyl) imidazole compound with a halogenating agent such as an N-chlorosuccinimide, an N-bromosuccinimide, a chlorinated isocyanuric acid compound or the like compound.

We have identified GR138950, a potent antagonist of the angiotensin II receptor with high oral bioavailability, as our second drug candidate to GR117289. Using GR117289, a compound with moderate bioavailability (20%) in man as a lead, we pursued a strategy aimed at enhancing bioavailability. The strategy was based on SAR established around the diacid GR117289, and from this, it was proposed that a monoacid, in particular a trifluoromethanesulfonamide, should be better absorbed after oral administration and have enhanced oral bioavailability. This led to the identification of GR138950, a potent antihypertensive agent in the renal hypertensive rat, causing sustained falls in blood pressure after oral administration. Oral bioavailability of GR138950 in rats and dogs is high, confirming that GR138950 is well absorbed after oral administration. Moreover, the low plasma clearance and long plasma half-life suggest that this compound will be suitable for once a day administration. Furthermore, the preliminary data indicate that the high bioavailability of GR138950 seen in rats and dogs translates to man. These results demonstrate clearly that GR138950 has the potential to be a clinically effective antihypertensive agent. Further studies are in progress to evaluate GR138950 in the treatment of hypertension.
