Background: In the past decade CADD has emerged as a rational approach in drug development so with the help molecular docking approach we planned to perform virtual screening of the designed data set of Schiff bases of cinnamaldehyde. The research work will be helpful to put some light on the drug receptor interactions required for anti-inflammatory activity. Methods: For carrying out virtual screening of the developed cinnamaldehyde Schiff base data set, AutoDock 4.0 was used. The active hits identified through in silico screening were synthesized. Anti-inflammatory evaluation was carried out using Carrageenan-induced paw oedema method. Results: Compounds V2A44, V2A55, V2A76, V2A82, V2A119, V2A141 and V2A142 has shown highest binding energy (-4.84, -4.76, -4.59, -4.78, -4.74, -4.85 and -4.72 kcal/mol, respectively) and the binding interactions with amino acids namely, Phe478, Glu479, Lys492, Ala493, Asp497 and Ile498. Some of the analogs have shown significant activity and were comparable to Indomethacin (standard drug). Conclusion: Five new compounds have shown significant activity and the results obtained from in silico studies are parallel to those of in vivo studies.

Thrombomodulin (TM) and matrix metalloproteinase (MMPs) are the major factors that are responsible for lung cancer. Hence, the identification of novel compounds inhibiting TM and MMPs is the challenging task for the scientists. Even though synthetic drugs were developed, their toxicity and offtarget limit their usage. The current study aims to investigate the molecular simulations for bacterial derived stearic acid to estimate the in silico anticancer activity against TM and MMPs protein as target compounds and the findings were correlated with the standard drug vorinostat. Using Lamarckian genetic algorithm, the TM and MMPs were energy minimized and docked with stearic acid and vorinostat using auto dock 4.2 and visualized in PyMol software. Protein and ligand binding analysis revealed that stearic acid interacts with the amino acids of MMPs residues of PHE83, SER212, ALA213 and ASN214. It interacts with the TMs with two amino acid residues i.e. CYS407 and GLU408. Hence, compared to vorinostat, stearic acid shows a higher binding affinity towards MMPs and slightly lower affinity towards TM proteinase. We conclude that the computational analysis of ligand binding interaction of stearic acid suggests that it could be a potential inhibitor of matrix metallo proteinase and is effective against thrombomodulin and can be considered as an anticancer agent by in vivo studies.

Abstract The present piece of research work is framed as improving the solubility of ketoprofen by forming co-crystal using fumaric acid as a coformer. Co-crystal of ketoprofen and fumaric acid were prepared by simple solvent assisted grinding. The independent variables i.e. drug and coformer were mixed in 1:1 molar ratio and dependent variables were assumed to be solubility and % drug release. Differential scanning calorimetry, fourier transform infrared spectroscopy, X-ray diffraction, nuclear magnetic resonance and scanning electron microscopy techniques were used to characterize the preparation of optimized batch of co-crystal and further, evaluated for in-vitro and in-vivo anti-inflammatory and analgesic activities. Based on results of solubility and dissolution rate studies the drug showed 4-5 fold improvement in both the properties on co-crystallisation. The values of Gibbs free energy are negative at all levels of carrier demonstrating spontaneity of drug solubilization process. The IC50 value of optimized batch of co-crystal formulation and pure drug was observed as 327.33 µg/ml and 556.11 µg/ml, respectively, demonstrating that co-crystal formulation possesses more percentage protection against protein denaturation than the drug ketoprofen. In-vivo (anti-inflammatory and analgesic) activities revealed that optimized batch of co-crystal formulation delivered a rapid pharmacological response in wistar rats and albino mice when compared with standard drug.

Temu kunci (Boesenbergia pandurata ROXB. SCHLECHT) is one of Indonesia medicinal plants which contains essential oils and flavonoids and it has interesting pharmacological activities, such as antifungal, antibacterial, antioxidant, anti-inflammatory and anti-cancer. It also contains pinostrobin which potent as anti-inflammatory and analgesic activities through inhibition of COX-2 enzymes. This research was to obtain pinostrobin derivatives of acylation reactions between pinostrobin and acyl chloride derivatives. The structure modifications of pinostrobin were obtained by Schotten-Baumann method through nucleophilic substitution reactions between pinostrobin and acyl chloride derivatives. Their structure had analyzed using the spectrophotometric analysis (NMR, IR, and GC/MS). The investigation of structure modifications of pinostrobin (1) from this plant has demonstrated the presence of pinostrobin acetate (2) and new pinostrobin propionate (3). The 2 and 3 are derivatives of pinostrobin that can be synthesized using the Schotten-Baumann method to yield 84.3% and 73.9%, respectively. The results of in silico study between pinostrobin and pinostrobin acyl derivatives on the COX-2 receptor with a PDB code: 1PXX showed that pinostrobin RS value was -87.18kcal/mol, while pinostrobin propionate had a RS value of -98.61 kcal/mol. It can be predicted that the pinostrobin acyl derivative has greater analgesic activity than pinostrobin, so it is feasible to be developed and carried out research on its analgesic activity in vivo.

The objective of our present study is to scrutinize the analgesic and anti-inflammatory potentials of essential oil of Eucalyptus camaldulensis leaf using different in vivo assay models at doses of 100, 200, and 400 mg/kg body weight. Twenty chemical compounds, which were isolated from the leaves essential oil of E. camaldulensis, were docked using AutodockVina against cyclooxygenase 2, tumor necrosis factor-α, and interleukin-1β convertase to elucidate the analgesic and anti-inflammatory activity. The essential oil of E. camaldulensis exhibited noteworthy analgesic activities in the writhing test. In the tail immersion and hot-plate test, the essential oil significantly extended the latency period. The number of licks in the formalin-induced paw licking test was markedly reduced following essential oil administration. In addition, E. camaldulensis essential oil revealed notable anti-inflammatory responses in carrageenan-induced paw edema, xylene induced ear edema and cotton pellet induced granuloma methods. Among 20 compounds, 5 ( cis-sabinol, globulol, α-eudesmol, β-eudesmol, and γ-eudesmol) showed better binding for cyclooxygenase-2 while β-eudesmol exhibited higher affinity for TNFα than that of TNF-alpha-IN-1 and standard drug. In the case of interleukin 1β convertase, maximum affinity was shown by α-eudesmol than the synthetic drug belnacasan. Chemical components of the essential oil interacted with diverse amino acid residues which were similar to the natural substrate and standard drugs. In conclusion, E. camaldulensis essential oil can be an effective source of analgesic and anti-inflammatory treatment and additional modification and docking studies will be required to justify the efficiency of globulol, α-eudesmol, β-eudesmol, and γ-eudesmol.
