Pant S, Nain S. Recent Advances in the Development of Pyrimidine-based CNS Agents. Curr Drug Discov Technol 2023; 20:14-28. [PMID: 36200187 DOI: 10.2174/1570163819666221003094402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 07/02/2022] [Accepted: 08/25/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND In the past few decades, considerable progress has been made in CNS drug discovery, and various new CNS agents have been developed. Pyrimidine is an important scaffold in the area of medicinal chemistry. Recently, pyrimidine-containing compounds have been successfully designed as potent CNS agents. Substantial research has been carried out on pyrimidine-bearing compounds to treat different disorders of CNS in various animal models. METHODS Utilizing various databases, including Google Scholar, PubMed, Science Direct, and Web of Science, the literature review was conducted. The specifics of significant articles were discussed with an emphasis on the potency of pyrimidines derivatives possessing CNS activity. RESULTS Recent papers indicating pyrimidine derivatives with CNS activity were incorporated into the manuscript. (46) to (50) papers included different pyrimidine derivatives as 5-HT agonist/antagonists, (62) to (67) as adenosine agonist/antagonist, (70) to (75) as anticonvulsant agents, (80) to (83) as cannabinoid receptor agonists, (102) to (103) as nicotinic and (110) as muscarinic receptor agonists. The remaining papers (113) to (114) represented pyrimidine-based molecular imaging agents. CONCLUSION Pyrimidine and its derivatives have been studied in detail to evaluate their efficacy in overcoming multiple central nervous system disorders. The article covers the current updates on pyrimidine-based compounds as potent CNS and molecular imaging agents and will definitely provide a better platform for the development of potent pyrimidine-based CNS drugs in the near future.

Abstract
Background: Benzimidazole and piperidine rings are important pharmacophore groups
for drug design studies.
</P><P>
Objective: In this study, we aimed to investigate the antidepressant-like activity of some 2-(4-
substituted-phenyl)-1-[2-(piperidin-1-yl)ethyl]-1H-benzimidazole derivatives.
</P><P>
Methods: Tail-suspension Test (TST) and Modified Forced Swimming Tests (MFST) were used to
assess antidepressant-like activities of the test compounds. Moreover, locomotor activity performances
of the animals were evaluated by an activity cage device.
</P><P>
Results: In the TST and MFST, compounds 2c-2h (10 mg/kg) and the reference drug fluoxetine (20
mg/kg) significantly reduced the immobility time of mice indicating the antidepressant-like activities
of these compounds. Further, in MFST, the same compounds induced significant enhancement
in the duration of active swimming behaviors without affecting the climbing performance of the
animals. This prolongation in the swimming time, similar to fluoxetine, pointed out that antidepressant-
like activity of the compounds 2c-2h might be related to the serotonergic rather than noradrenergic
mechanisms. Besides, results of the activity cage tests demonstrated that none of the tested
compounds caused an alteration in the locomotor activities of mice, signifying that antidepressantlike
effects presented in this study were specific.
</P><P>
Conclusion: In conclusion, results of this present study supported the previous papers reporting the
therapeutic potential of compounds carrying benzimidazole and/or piperidine rings in their structure
and emphasized, once again, the importance of these pharmacophore groups in drug design studies.

Discovery of benzimidazole derivatives as orally active renin inhibitors: Optimization of 3,5-disubstituted piperidine to improve pharmacokinetic profile. Bioorg Med Chem 2018; 26:3261-3286. [PMID: 29754833 DOI: 10.1016/j.bmc.2018.04.051] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Revised: 04/25/2018] [Accepted: 04/26/2018] [Indexed: 11/29/2022]
Abstract
We previously identified 2-tert-butyl-4-[(3-methoxypropyl)amino]-N-(2-methylpropyl)-N-[(3S,5R)-5-(morpholin-4-ylcarbonyl)piperidin-3-yl]pyrimidine-5-carboxamide 3 as a potent renin inhibitor. Since 3 showed unacceptably low bioavailability (BA) in rats, structural modification, using SBDD and focused on physicochemical properties was conducted to improve its PK profile while maintaining renin inhibitory activity. Conversion of the amino group attached at the 4-position of pyrimidine to methylene group improved PK profile and decreased renin inhibitory activity. New central cores with carbon side chains were explored to improve potency. We had designed a series of 5-membered azoles and fused heterocycles that interacted with the lipophilic S3 pocket. In the course of modification, renin inhibitory activity was enhanced by the formation of an additional hydrogen bonding with the hydroxyl group of Thr77. Consequently, a series of novel benzimidazole derivatives were discovered as potent and orally bioavailable renin inhibitors. Among those, compound 13 exhibited more than five-fold of plasma renin inhibition than aliskiren in cynomolgus monkeys at dose ratio.

Abstract
The popularity of fragment-based drug discovery (FBDD) is demonstrated by the number of recent successful fragment-to-lead (F2L) publications. This Miniperspective provides a tabulated summary of the F2L literature published in the year 2016, along with discussion of general trends. It uses the same format as our summary of the 2015 literature and is intended to be a resource for both FBDD practitioners and medicinal chemists in general.

Abstract
The aspartic proteinase renin is an attractive target for the treatment of hypertension and cardiovascular/renal disease such as chronic kidney disease and heart failure. We introduced an S1' site binder into the lead compound 1 guided by structure-based drug design (SBDD), and further optimization of physicochemical properties led to the discovery of benzimidazole derivative 10 (1-(4-methoxybutyl)-N-(2-methylpropyl)-N-[(3S,5R)-5-(morpholin-4-yl)carbonylpiperidin-3-yl]-1H-benzimidazole-2-carboxamide hydrochloride, TAK-272) as a highly potent and orally active renin inhibitor. Compound 10 demonstrated good oral bioavailability (BA) and long-lasting efficacy in rats. Compound 10 is currently in clinical trials.
