- Discovery of TD-0212, an Orally Active Dual Pharmacology AT1 Antagonist and Neprilysin Inhibitor (ARNI)
-
Dual inhibition of angiotensin-converting enzyme (ACE) and neprilysin (NEP) by drugs such as omapatrilat produces superior antihypertensive efficacy relative to ACE inhibitors but is associated with a higher risk of life-threatening angioedema due to bradykinin elevations. We hypothesized that dual AT1 (angiotensin II type 1 receptor) blockade and NEP inhibition with a single molecule would produce similar antihypertensive efficacy to omapatrilat without the risk of angioedema since ACE (the rate limiting enzyme in bradykinin metabolism) would remain uninhibited. Merging the structures of losartan (an AT1 antagonist) and thiorphan (a NEP inhibitor) led to the discovery of a novel series of orally active, dual AT1 antagonist/NEP inhibitors (ARNIs) exemplified by compound 35 (TD-0212). In models of renin-dependent and -independent hypertension, 35 produced blood pressure reductions similar to omapatrilat and combinations of AT1 receptor antagonists and NEP inhibitors. Upper airway angioedema risk was assessed in a rat tracheal plasma extravasation (TPE) model. Unlike omapatrilat, 35 did not increase TPE at antihypertensive doses. Compound 35 therefore provides the enhanced activity of dual AT1/NEP inhibition with a potentially lower risk of angioedema relative to dual ACE/NEP inhibition.

- The discovery of new potent non-peptide Angiotensin II AT1 receptor blockers: A concise synthesis, molecular docking studies and biological evaluation of N-substituted 5-butylimidazole derivatives
-
A convenient and facile synthesis, in silico docking studies and in vitro biological evaluation of N-substituted 5-butylimidazole derivatives as potent Angiotensin II (ANG II) receptor type 1 (AT1) blockers (ARBs) has been reported in the current study. Our efforts have been directed towards the development of an efficient synthetic route allowing the facile introduction of substituents on the imidazole ring. In particular, a series of imidazole based compounds bearing the biphenyl moiety at the N - 1 position, a halogen atom at the C-4 and polar substituents such as hydroxymethyl, aldo or carboxy group at the C-2 position were designed and synthesized. These compounds were evaluated for binding to human AT1 receptor and for ANG II antagonism in vitro on isolated rat uterus. Among them, 5-butyl-1-[[2′-(2H-tetrazol-5-yl)biphenyl-4-yl] methyl]imidazole-2-carboxylic acid (30) exhibited higher binding affinity compared to the other analogues tested (-log IC50 = 8.46). The latter analogue was also found to be the most active in the rat uterotonic test (pA2 = 7.83). Importantly, the binding affinity was higher to that of losartan (-log IC50 = 8.25) indicating the importance of carboxy group at the C-2 position. Experimental findings are in good agreement with docking studies, which were undertaken in order to investigate ligand/AT1 receptor interactions.

- A modification to the synthesis of Telmisartan: An antihypertensive drug
-
A highly efficient approach to the synthesis of Telmisartan is described. Directed ortho-metalation of 4,4-dimethyl-2-phenyl-4,5-dihydrooxazole provided the key organozinc intermediate for a palladium catalysed biaryl coupling with 3′-(4-bromobenzyl)-1,7′-dimethyl-2′-propyl-1 H,3′ H-2,5′-bibenzo[d]imidazole which was obtained from alkylation of 1,7′-dimethyl-2′-propyl-1 H,3′H-2,5′-bibenzo[d] imidazole. This methodology overcomes many of the drawbacks associated with previously reported syntheses.

- A novel 3-substituted benzazepinone growth hormone secretagogue (L- 692,429)
-
The 3-substituted benzazepinone, L-692,429 (compound 1), is the prototype compound of a novel class of compounds that stimulate release of growth hormone (GH). The molecule evolved from efforts to identify a non-peptide mimic of the growth hormone-releasing hexapeptide, GHRP-6. Compound 1 is prepared by sequential attachment of dimethyl-β-alanine and 2'- biphenylyltetrazole side chains to a chiral 3-aminobenzolactam nucleus. Comparison of the biological activity of 1 with the corresponding six- and eight-membered lactam analogs shows the seven-membered benzazepinone skeleton to be preferred. Molecular modeling of the structurally diverse GH secretagogues, L-692,429 and GHRP-6, was performed.

- Synthesis and Structure-Activity Relationships of Nonpeptide, Potent Triazolone-Based Angiotensin II Receptor Antagonists
-
2,5-Dibutyl-2,4-dihydro-4--4'-yl>methyl>-3H-1,2,4-triazol-3-one, SC-51316, was synthesized as a potent and orally active angiotensin II (AII) receptor antagonist with a long duration of action.To explore the lipophilic pocket in the AII receptor interacting with the substituent at the 2-position of triazolone-based antagonists, a series of compounds were prepared and evaluated for receptor binding affinity and antagonism of AII-contracted rabbitaortic rings.It has been found that the pocket is very spacious and can accommodate different sizes of lipophilic groups and various functionalities.Acidic groups generally result in a slight decrease in binding affinity.Branched chains are unfavorable.The freedom of rotation around C2-C3 in the flexible side chain is crucial for good binding.The 2-phenylethyl-substituted triazolone analogue exhibits the highest in vitro potency among all compounds that have been synthesized.

- Nonpeptide Angiotensin II Receptor Antagonists: The Discovery of a Series of N-(Biphenylylmethyl)imidazoles as Potent, Orally Active Antihypertensives
-
A new series of nonpeptide angiotensin II (AII) receptor antagonists has been prepared.These N-(biphenylylmethyl)imidazoles, e.g. 2-butyl-1--4-chloro-5-(hydroxymethyl)imidazole, differ from the previously reported N-(benzamidobenzyl)imidazoles and related compounds in that they produce a potent antihypertensive effect upon oral administration; the earlier series generally were active only when administered intravenously.It has been found that the acidic group at the 2'-position of the biphenyl is essential.Only ortho-substituted acids possess both high affinity for the AII receptor and good oral antihypertensive potency.The carboxylic acid group has been replaced with a variety of acidic isosteres, and the tetrazole ring has been found to be the most effective.The tetrazole derivative, DuP 753, is currently in development for the treatment of hypertension.
