An in silico study on pulmonary fibrosis inhibitors from Tinospora cordifolia and Curcuma longa targeting TGF-beta RI.[Pubmed:35068362]

J Biomol Struct Dyn. 2022 Jan 24:1-17.

Pulmonary fibrosis is characterized by damage to the epithelial cells and alveolar-capillary basement membrane. The increased expression levels of transforming growth factor beta (TGF-beta) and TGF-beta-receptor-1 induced differentiation of lung fibroblasts to myofibroblasts, an alarming sign and considered the hallmark event development of pulmonary fibrosis. In the current study, the stability of phytochemicals of Curcuma longa and Tinospora cordifolia as inhibitors of transforming growth factor beta RI (TGF-beta RI) were evaluated using molecular docking and molecular dynamics studies. A total of 108 Curcuma longa and 16 Tinospora cordifolia constituents were screened against TGF-beta RI as the target. Further, their ADMET properties were evaluated using the pkCSM online server. The compounds Tembetarine, magnoflorine from T. cordiolia, and 2-(Hydroxymethyl) anthraquinone and quercetin in C. longa showed significant binding affinities bonding interactions with the target, TGF-beta RI, and the study was compared with the known inhibitors from the literature. The MD simulations study also supported that the selected compounds show a close affinity with the binding site and maintained stable behavior throughout the simulation time. The pharmacophore feature analysis of the selected compounds and inhibitors were analyzed using the pharmagist web server, and the common features like H-bond donor and aromatic ring were mapped.Communicated by Ramaswamy H.

In silico analysis of phytoconstituents from Tinospora cordifolia with targets related to diabetes and obesity.[Pubmed:33442530]

In Silico Pharmacol. 2021 Jan 2;9(1):3.

Traditionally, Tinospora cordifolia is commonly used in the treatment of diabetes and obesity; has been evaluated for their anti-diabetic and anti-obese potency in experimental animal models. However, the binding affinity of multiple bioactives with various proteins involved in the pathogenesis of diabetes and obesity has not been reported yet. Hence, the present study aimed to assess the binding affinity of multiple bioactives from T. cordifolia with various targets involved in the pathogenesis of diabetes and obesity. The ligands and targets were retrieved from the PubChem and Protein Data Bank respectively and docked using autodock4.0. Druglikeness and absorption, distribution, metabolism, excretion, and toxicity profile were predicted using Molsoft and admetSAR1 respectively. The multiple bioactives from T. cordifolia were identified to interact with multiple proteins involved in the pathogenesis of diabetes/obesity, i.e., isocolumbin (- 9 kcal/mol) with adiponectin (PDB: 4DOU), beta-sitosterol (- 10.9 kcal/mol) with cholesteryl ester transfer protein (PDB: 2OBD), tinocordiside (- 6.9 kcal/mol) with lamin A/C (PDB: 3GEF), berberine (- 9.5 kcal/mol) with JNK1 (PDB:3ELJ), beta-sitosterol & isocolumbin (- 10.1 kcal/mol) with peroxisome proliferator-activated receptor-gamma (PDB:4CI5), berberine (- 7.5 kcal/mol) with suppressor of cytokine signaling 3 (PDB: 2BBU), isocolumbin (- 9.6 kcal/mol) with pancreatic alpha-amylase (PDB: 1B2Y), isocolumbin (- 9 kcal/mol) with alpha-glucosidase (PDB: 3TOP), and beta-sitosterol (- 10.8 kcal/mol) with aldose reductase (PDB: 3RX2). Similarly, among the selected bioactives, Tembetarine scored highest druglikeness score, i.e., 1.21. In contrast, isocolumbin scored lowest drug-likeness character i.e. - 0.52. The predicted result of phytochemicals from T. cordifolia for acute oral toxicity, rat acute toxicity, fish toxicity, drug-likeness score, and aqueous solubility showed the probability of lower side/adverse effects in human consumption. The study suggests processing for bioactives from T. cordifolia against diabetes and obesity via in-vitro and in-vivo approaches.

Screening of phytochemical compounds of Tinospora cordifolia for their inhibitory activity on SARS-CoV-2: an in silico study.[Pubmed:32627715]

J Biomol Struct Dyn. 2021 Sep;39(15):5799-5803.

In the present study, we explored phytochemical constituents of Tinospora cordifolia in terms of its binding affinity targeting the active site pocket of the main protease (3CL pro) of SARS-CoV-2 using molecular docking study and assessed the stability of top docking complex of tinosponone and 3CL pro using molecular dynamics simulations with GROMACS 2020.2 version. Out of 11 curated screened compounds, we found the significant docking score for tinosponone, xanosporic acid, cardiofolioside B, Tembetarine and berberine in Tinospora cordifolia. Based on the findings of the docking study, it was confirmed that tinosponone is the potent inhibitor of main protease of SARS-CoV-2 with the best binding affinity of -7.7 kcal/mol. Further, ADME along with toxicity analysis was studied to predict the pharmacokinetics and drug-likeness properties of five top hits compounds. The molecular dynamics simulation analysis confirmed the stability of tinosponone and 3CL pro complex with a random mean square deviation (RMSD) value of 0.1 nm. The computer-aided drug design approach proved that the compound tinosponone from T. cordifolia is a potent inhibitor of 3CL main protease of SARS-CoV-2. Further, the in vitro and in vivo-based testing will be required to confirm its inhibitory effect on SARS-CoV-2.Communicated by Ramaswamy H. Sarma.

Anti-inflammatory and antinociceptive activities of Croton urucurana Baillon bark.[Pubmed:26944237]

J Ethnopharmacol. 2016 May 13;183:128-135.

ETHNOPHARMACOLOGICAL RELEVANCE: Croton urucurana (Euphorbiaceae) is popularly used in Brazil to treat inflammatory processes, pain, and gastric ulcers. AIM OF STUDY: To evaluate the anti-inflammatory and antinociceptive properties of the methanol extract from the bark of C. urucurana (MECu) in mice and identify its chemical constituents. MATERIALS AND METHODS: The extract was characterized by UHPLC-DAD-ESI-Q-TOF-MS/MS. Extract doses of 25, 100, and 400mg/kg were employed in the biological assays. Evaluation of anti-inflammatory activity was based on paw edema and leukocyte recruitment into the peritoneal cavity of mice, both induced by carrageenan. Abdominal writhing caused by acetic acid and duration of formalin-induced paw-licking were the models employed to evaluate antinociceptive activity. RESULTS: Ten compounds were identified in the extract: (+)-gallocatechin (1), procyanidin B3 (2), (+)-catechin (3), (-)-epicatechin (4), Tembetarine (5), magnoflorine (6), taspine (7), methyl-3-oxo-12-epi-barbascoate (8), methyl-12-epi-barbascoate (9), and hardwickiic acid (10). This is the first report of compounds 2, 4, 6, 7, and 10 in C. urucurana and compound 5 in the genus Croton. In addition to inhibiting paw edema and leukocyte recruitment (particularly of polymorphonuclear cells) into the peritoneal cavity of mice, MECu reduced the number of abdominal writhings induced by acetic acid and the duration of formalin-induced paw licking. CONCLUSIONS: The methanol extract of C. urucurana bark exhibited anti-inflammatory and antinociceptive properties, corroborating its use in folk medicine. These effects may be related to the presence of diterpenes, alkaloids, and flavonoids.

Studies on the alkaloids of the bark of Magnolia officinalis: isolation and on-line analysis by HPLC-ESI-MS(n).[Pubmed:23823874]

Molecules. 2013 Jul 3;18(7):7739-50.

The bark of Magnolia officinalis is a well-known Traditional Chinese Medicine. In the present study, two new alkaloids, named (S)-4-keto-magnoflorine (6) and (R)-3,4-dehydromagnocurarine (11), together with seven known alkaloids: (S)-magnoflorine (5), trans/cis N-feruloylputrescine (7/8), (R)-magnocurarine (10), (S)-Tembetarine (12), (R)-oblongine (14), and (R)-asimilobine (17) were isolated and their structures elucidated by spectroscopic methods, including 1D, 2D NMR, and HRESI-MS. The absolute configurations of the isoquinoline alkaloids 5, 6, 10-12, 14, and 17 were determined by CD. In vitro inhibitory activities against aldose reductase, lipase, alpha-glucosidase, DPP-IV and three cancer cell lines (A549, Bel-7402, and HCT-8) were evaluated for all isolated compounds. However, all compounds showed weak activities in all tests at the same concentration as the positive control drugs. An HPLC-ESI-MS(n) method has been established for screening of alkaloids in the bark of M. officinalis. A total of 23 alkaloids were identified or tentatively characterized; including 13 aporphines, eight benzylisoquinolines and two amides. Plausible fragmentation pathways of the representative compounds 6, 7/8, 11, and 17 were proposed in the present study.
