Synthesis and identification of new sacubitril derivatives as lead compounds for antibacterial, antifungal and antitubercular (TB) activities against dormant tuberculosis. RSC Adv 2023; 13:13540-13546. [PMID: 37152580 PMCID: PMC10155492 DOI: 10.1039/d3ra00713h] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Accepted: 04/13/2023] [Indexed: 05/09/2023] Open
Abstract
We identified twenty-two new sacubitril derivatives (5a-v) as lead compounds for various biologically active targets. These compounds were synthesized by reacting an intermediate compound (2R,4S)-5-([1,1'-biphenyl]-4-yl)-4-(amino)-2-methylpentanoic acid ethyl ester hydrochloride with respective carboxylic acid (RCOOH). The molecular structures of all the newly synthesized compounds were determined by 1H and 13C NMR, ESI mass spectrometry, FTIR spectroscopy, and CHN analysis. Moreover, compound 5n was characterized by a single-crystal X-ray diffraction (SXRD) study to confirm the structure obtained from spectral data. All these compounds were screened for various biological functions such as antifungal, antibacterial, and anti-TB activities. Among these twenty-two compounds (5a-v), some exhibited good to moderate anti-bacterial properties. Similarly, some compounds showed moderate anti-TB and antifungal activities. In addition, the anti-TB activity of compound 5q was estimated against M. tuberculosis in a nutrient starvation model (NSM). Similarly, toxicity was examined against RAW 264.7 cells. These biological activity studies were also correlated with molecular docking studies.

Phenolic furanochromene hydrazone derivatives: Synthesis, antioxidant activity, ferroptosis inhibition, DNA cleavage and DNA molecular docking studies. Bioorg Med Chem 2022; 75:117088. [PMID: 36372027 DOI: 10.1016/j.bmc.2022.117088] [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: 07/09/2022] [Revised: 09/19/2022] [Accepted: 11/01/2022] [Indexed: 11/08/2022]
Abstract
Twenty-four phenolic furanochromene hydrazone derivatives were designed and synthesized in order to evaluate structure-activity relationships in a series of antioxidant-related assays. The derivatives have varying substitution patterns on the phenol ring, with some compounds having one, two or three hydroxy groups, and others containing one hydroxy group in combination with methoxy, methyl, bromo, iodo and/or nitro groups. Antioxidant activity was determined using the DPPH free radical scavenging and CUPRAC assays. Compounds containing ortho-dihydroxy and para-dihydroxy patterns had the highest free radical scavenging activity, with IC50 values ranging from 5.0 to 28 μM. Similarly, derivatives with ortho-dihydroxy and para-dihydroxy patterns, together with a 4-hydroxy-3,5‑dimethoxy pattern, displayed strong copper (II) ion reducing capacity, using Trolox as a standard. Trolox equivalent antioxidant capacity (TEAC) coefficients for these derivatives ranged from 1.75 to 3.97. As further evidence of antioxidant potential, greater than half of the derivatives reversed erastin-induced ferroptosis in HaCaT cells. In addition, twenty-three of the derivatives were effective at cleaving supercoiled plasmid DNA in the presence of copper (II) ions at 1 mM, with the 3,4‑dihydroxy derivative showing cleavage to both the linear and open circular forms at 3.9 uM. The interaction of the phenolic furanochromene derivatives with DNA was confirmed by molecular docking studies, which revealed that all the derivatives bind favorably in the minor groove of DNA.

Abstract
A series of 30 novel diamino phenyl chloropicolinate fettered carboxamides, urea, and thiourea derivatives were synthesized by coupling of methyl 4-amino-6-(2-aminophenyl)-3-chloropyridine-2-carboxylate with different acid chlorides, urea, and thiourea moieties, respectively. All of these compounds were characterized by 1H and 13C nuclear magnetic resonance spectroscopy, CHN analysis, and high-resolution mass spectra for confirmation of the structures. Two compounds were also characterized by single-crystal X-ray diffraction analysis to confirm the structures obtained by spectral analysis. All these 30 compounds were tested for their in vitro antimycobacterial activity using the microplate alamar blue assay method against Mycobacterium tuberculosis. Five compounds have shown good minimum inhibitory concentration (MIC) values with low cytotoxicity when compared with the reference drugs. Moreover, some of the compounds have high MIC values compared with isoniazid, rifampicin, and so forth and also had shown good reign in the spread of bacteria by the nutrient starvation model. These antimycobacterial activity results have shown a good correlation with molecular docking model analysis with the inhibitors MurB by exhibiting strong interactions. Some of these compounds could be promising candidates against M. tuberculosis for future preclinical agent drug development.

Abstract
Background:
Heterocyclic compounds containing heteroatoms (O, N and S) as part of
five or six-membered cyclic moieties exhibited various potential applications, such as
pharmaceutical drugs, agrochemical products and organic materials. Among many known
heterocyclic moieties, quinoline and its derivatives are one of the privileged scaffolds found in many
natural products. In general, quinoline derivatives could be prepared by utilizing ortho-substituted
anilines and carbonyl compounds containing a reactive α-methylene group of well-known reaction
routes like Friedlander synthesis, Niemantowski synthesis and Pfitzinger synthesis. Moreover,
polysubstituted quinolones and their derivatives also had shown considerable interest in the fields of
organic and pharmaceutical chemistry in recent years.
Objective:
The main objective of our research work is towards the design and synthesis of
divergent biological-oriented, proactive analogues with potential pharmacological value inspired by
the anti-tubercular activity of 2-phenylquinoline analogues. In this study, we have been interested in
the design and synthesis of bioactive, 2, 4-diphenyl, 8-arylated quinoline analogues.
Methods:
6-phenyl-6h-chromeno [4, 3-b] quinoline derivatives were synthesized from 4-chloro-2-
phenyl-2H-chromene-3-carbaldehyde and various substituted aromatic anilines as starting materials
using sodium bisulfate embedded SiO2 re-usable catalyst. All these fifteen new compound structures
confirmed by spectral data 1H & 13C NMR, Mass, CHN analysis etc. Furthermore, all these new
compounds antibacterial activity strains recorded using the paper disc method. The compound
molecular structures were designed using molecular docking study by utilizing the crystallographic
parameters of S. Areus Murb protein.
Results:
A series of fifteen new quinoline derivatives synthesized in moderate to good yields using
sodium bisulfate embedded SiO2 re-usable catalyst. The molecular structures of these newly
synthesized compounds elucidated by the combination of spectral data along with the elemental
analysis. These compounds antibacterial activity study have shown moderate to good activity against,
Escherichia coli (Gram-negative) and Staphylococcus aureus (gram-positive) organisms. These
antibacterial activity results were also a very good correlation with molecular docking studies.
Conclusion:
In this study, fifteen new quinoline derivatives synthesized and structures confirmed by
spectral data. In fact, all the compounds have shown moderate to good antibacterial activity. In
general, the compounds containing the electron donor group at R1 position (R1 = OMe) and the
acceptor group at R2 positions (R2 = F or Cl) had shown good antibacterial activity. These antibacterial
activity results were also a very good correlation with molecular docking studies showing strong
binding energies with the highest value being, -12.45 Kcal mol-1 with S. aureus MurB receptor.

Diversity-oriented generation and biological evaluation of new chemical scaffolds bearing a 2,2-dimethyl-2H-chromene unit: Discovery of novel potent ANO1 inhibitors. Bioorg Chem 2020; 101:104000. [PMID: 32592976 DOI: 10.1016/j.bioorg.2020.104000] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2019] [Revised: 04/21/2020] [Accepted: 06/03/2020] [Indexed: 02/07/2023]
Abstract
Chemical territory bearing a 2,2-dimethyl-2H-chromene motif was expanded by utilizing an o-hydroxy aldehyde group of 5-hydroxy-2,2-dimethyl-2H-chromene-6-carbaldehyde as a synthetic handle to install distinctive morphology and functionality of each scaffold. Cell based assays and in silico docking analysis led us to discover that these new compounds exhibit inhibitory effect on anoctamin1 (ANO1). ANO1 is amplified and highly expressed in various carcinomas including prostate cancer, esophageal cancer, breast cancer, and pancreatic cancer. Biological assays revealed that (E)-1-(7,7-dimethyl-7H-furo[2,3-f]chromen-2-yl)-3-(1H-pyrrol-2-yl)prop-2-en-1-one (3n, Ani-FCC) is a novel, potent and selective ANO1 inhibitor with an IC50 value of 1.23 μM. 3n showed 144 times stronger activity on ANO1 inhibition than ANO2 inhibition and did not alter the chloride channel activity of CFTR and the intracellular calcium signaling. Notably, 3n strongly decreased cell viability of PC-3 and FaDu cells expressing high levels of ANO1 with a decrease in ANO1 protein levels. In addition, 3n significantly enhanced apoptosis via activation of caspase 3 and cleavage of PARP in PC-3 and FaDu cells. This study shows that a novel ANO1 inhibitor, 3n, can be a potential candidate for the treatment of cancers overexpressing ANO1, such as prostate cancer and esophageal cancer.
