A study has been undertaken with an aim to isolate potent endophytic fungi from mangrove plant Lumnitzera racemosa Linn. Among the 10 different fungal strains isolated, one potent strain with broad-spectrum antagonistic activity was found. Basing on the morphological, cultural and molecular characteristics, the potent fungal strain was identified as Cladosporium cladosporioides. Production of bioactive metabolites by the strain was high in Malt Extract Broth compared to other media tested. The culture utilized Mannitol and Beef extract as good carbon and Nitrogen sources for the elaboration of bioactive metabolites. The optimum pH and Temperature for bioactive metabolite production of the strain were recorded at 4.0 and 30 °C. The secondary metabolites produced by the strain grown under optimal conditions exhibited high antagonistic activity against gram-positive as well as Gram-negative bacteria and fungi. This is the first report of Cladosporium cladosporioides from mangrove plant Lumnitzera racemosa...

The main objective of this research work was to check the presence or absence of the phytochemical chemicals in all the selected medicinal plant. Phytochemical analysis of these plants confirm the presence of various phytochemicals like saponins, tannins, amino acids, phenols, carbohydrates, proteins, flavonoids, steroids, alkaloids and glycosides. A. catechu extract are analyzed by using TLC with varying solvent systems. It was another test Column chromatography, Chloroform: methanol (2:8) gave three and six fractions. In FTIR, the functional groups such as 1º, 2º amines, amides, carboxylic acids, alkanes, 1º amines, nitro compounds, aliphatic amines, and alkyl halides and searched the identity of secondary metabolites, which may act as 3,7-Diacetyl-1,5-Dimethyl-3,7-Di azabicyclo- [3,3,1] Nonan-9-One compound and clearly indicates that phytochemical. Chemical constituents of eleven compounds were identified in the methanol extract. The major components were 3, 7-Diacetyl-1, 5-Dimethyl-3, 7-Di azabicyclo- [3, 3, 1] Nonan-9-One (27.80 and C13H20O3N2). The results were obtained suggest that, in addition to their pharmaceutical and medicine sources of 3, 7-Diacetyl-1, 5-Dimethyl-3, 7-Di azabicyclo- [3, 3, 1] Nonan-9-One...

In the present investigation, the chalcone intermediates are synthesized by Claisen-Schmidt condensation reaction between acetanilide and appropriate aromatic aldehydes. Further, these chalcone intermediates were cyclized with phenylhydrazine in glacial acetic acid to give new pyrazolines derivatives using ultrasonic irradiation with higher yields in lesser time. All the synthesized derivatives are characterized by their TLC, Physical constant, FTIR, and 1H NMR. The Chalcone intermediates were screened for their antimicrobial activity while cyclized pyrazolines derivatives were screened in search of potential anti-inflammatory compounds. The compound 4c had shown good potential for anti-inflammatory...

The NSAIDs are popular in reducing acute and chronic inflammation as they have no abuse liability. QSAR (Quantitative structure-activity relationship) approach is a very useful and widespread technique for drug design. 2D QSAR models are based on descriptors derived from a two-dimensional graph representation of a molecule. The 2D QSAR study was performed on selected twenty-four compounds from synthesized indole derivatives for elucidating the structural requirements for COX-2 inhibition using multiple linear regression method. Statistically, significant models were generated using VLife Molecular Design Suite 3.5 software. The physicochemical parameters contributed significantly to biological activity. Amongst all the models generated, model 3 was found to be best with high r2 (squared correlation coefficient) of 0.9382. Model is robust as q2 (cross-validated squared correlation coefficient) value is also high as 0.8557 with good predictive power as indicated by pred_r2 = 0.7443. The model showed two alignment independent (AI) descriptors T_2_O_0 and T_2_N_7 as well as two physicochemical descriptors –ve Potential Surface Area and SA Most Hydrophobic contributing for activity. The present...

The entire plant (Monochoria vaginalis (Burm. f.) C. Presl.) except root is being used as a vegetable and has been used in traditional Indian system of medication for treating various diseases. But there are not many scientific data on the antioxidant and anticancer activity of M. vaginalis. Therefore, we aimed to determine the in-vitro antioxidant and anticancer activity of methanolic extract of M. vaginalis leaves. Standard biochemical methods evaluated the phytochemical investigation. In-vitro antioxidant activities of the methanolic extract of leaves were determined against DPPH, hydroxyl radical, reducing power assay, metal chelating activity, and hydrogen peroxide radicals. Also, we evaluated the anticancer activity of methanolic extract on Hep2 and HeLa lines by MTT calorimetric assay. Phytochemical analysis established the presence of rich secondary metabolites of total phenol (52.66 GAE mg/g), and flavonoids (305.88 QE mg/g). The methanolic extract of M. vaginalis exhibited strong antioxidant property (with IC50 value) against DPPH (52.24 mg/ml), hydroxyl radical (76.08 mg/ml), reducing power (58.15 mg/ml), metal chelating activity (35.70 mg/ml), and hydrogen peroxide scavenging...
