Computer-Guided total synthesis of natural products. Recent examples and future perspectives

Quantum chemical calculations of nuclear magnetic resonance (NMR) shifts and coupling constants have been extensively employed in recent years mainly to facilitate structural elucidation of organic molecules. When the results of such calculations are used to determine the most likely structure of a natural product in advance, guiding the subsequent synthetic work, the term ?computer-guided synthesis? could be coined. This review article describes the most relevant examples from recent literature, highlighting the scope and limitations of this merged computational/experimental approach as well.

Synthesis and characterization of novel anti-inflammatory poly(spiro thiazolidinone)s

Abstract: A new series of spirothiazolidinone polymers has been accomplished by solution polycondensation of 4,12-dioxa-1,9-dithiadispiro[4.2.4.2]tetradecane-3,11-dione (3) with different aliphatic and aromatic diamines. A model compound 4 was prepared by the reaction of spiro-monomer 3 with benzyl amine and was characterized by elemental and spectral analyses. These polymers were characterized by elemental and spectral analyses. The thermal properties of these polymers were investigated by thermogravimetric analysis and differential thermal analysis measurements. The morphological properties of selected polymers 5c and 5e were tested using scanning electron microscope to study their surface morphology. The molar masses of polymers 5a, 5b, and 5d were determined by gel permeation chromatography. In addition, the anti-inflammatory activities were studied for these spiro-polymers in comparison with the model compound by determination in vivo using acute carrageenan-induced paw edema in rats.

Biochemical indicators of nephrotoxicity in blood serum of rats treated with novel 4-thiazolidinone derivatives or their complexes with polyethylene glycol-containing nanoscale polymeric carrier

The aim of this study was to compare the effect of new synthetic 4-thiazolidinone derivatives (potential anticancer compounds denoted as 3882, 3288 and 3833) and doxorubicin (positive control) in free form and in their complexes with synthetic polyethylene glycol-containing nanoscale polymeric carrier on the biochemical indicators of nephrotoxicity in blood serum of rats. The concentration of total protein, urea, creatinine, glucose, ions of sodium, potassium, calcium, iron and chloride was measured. It was found that after injection of the investigated compounds, the concentration of sodium cations and chloride anions in blood serum was increased compared with control (untreated animals). Doxorubicin?s injection was accompanied by a decrease in the concentration of iron cations. The concentration of total protein, urea and creatinine decreased under the influence of the studied compounds. Complexation of these antineoplastic substances with a synthetic polymeric nanocarrier lowered the concentration of the investigated metabolites substantially compared to the effect of these compounds in free form. The normalization of concentration of total protein, urea and creatinine in blood serum of rats treated with complexes of the studied compounds with the polymeric carrier comparing with increased concentration of these indicators at the introduction of such compounds in free form was found.

Design, synthesis, and anticancer potential of the enzyme (PARP-1) inhibitor with computational studies of new triazole, thiazolidinone, – thieno [2, 3-d] pyrimidinones

Background: Thienopyrimidine, triazole and thiazolidinone derivatives have recently gained attention due to their effective pharmacological activities. They show antioxidant, antitumor, antimicrobial, antiviral, anti-inflammatory and analgesic properties. Objective: Synthesis of new ethyl 2-amino-4-isopropyl-5-methylthiophene-3-carboxylate (2) was used as a starting material to produce 2-mercapto-methylthienopyrimidinone (3), (4) and 2- hydrazinyl-methylthienopyrimidinone (5), through high yields and evaluating anticancer activities. Methods: A series of novel Schiff?s bases (6-9) were produced after treatment of (5) with aldehydes. Triazolopyrimidinones (6a, 7a, 8a, 9a) were produced from cyclization of benzylidene (6-9) using Br2 / AcOH or dry pyridine /Ac2O. Thiazolidinones (6b, 7b, 8b, 9b) were synthesized from benzylidene (6-9) with mercaptoacetic acid. Results: All the compounds were synthesized in good yields (55-85%) in a regularly actual system under mild condition. The new compounds have been established by means of diverse spectroscopic ways as IR, NMR and MS. The newly synthesized compounds were evaluated for their antiproliferative activity against the breast MCF-7 carcinoma cell line. Compound (7) showed promising anticancer activity with IC50 of 6.9 muM, and 40.8% of antioxidant effect as DPPH inhibition. Molecular docking of (7) showed deltaG values of-20.54 kcal/ mol and -25.60 kcal/ mol. Molecular dynamics simulation of (7) in complex with PARP-1 revealed RMSD of 3.00 a. Conclusion: The QSAR study confirmed the presence of a relationship between anticancer activity and subdivided surface area descriptors with coefficient r2 = 0.98 with high predictive power.

Synthesis, characterization and biological evaluation of thioureas, acylthioureas and 4-thiazolidinones as anticancer and antiviral agents

In this study, thiourea derivatives [1-4] were synthesized by using 2-amino-4-substituted pyridine compounds and these compounds have been used as the starting materials for synthesis of 2-imino-1,3-thiazolidin-4-one ring [5, 6]. Two different procedures for 4-thiazolidinone ring closure and synthesis method were optimized. The synthesized compounds were identified by the help of elemental analysis, IR, 1H-NMR, 13C-NMR and mass spectral data while the purities of them were proved with TLC. Synthesized compounds were evaluated for their antiviral and anticancer activity. Antiviral activity against Murine norovirus, Yellow fever, Enterovirus and Chikungunya strains of the test compounds were investigated and EC50 values of these compounds were determined higher than 0,3 muM. Cytotoxicity of test compounds was examined on NIH3T3 cell line. When the anticancer activity of test compounds was examined against PC-3, A549, HeLa, HT-29, MCF-7, SJSA1 and K562 cell lines, the percent proliferation values of these compounds were observed over 61% for all cell lines.
