Relationship between structural diversity and biological activities of flavonoids has remained an important discourse in the mainstream of flavonoid research. In the current study anti-angiogenic, cytotoxic, antioxidant and cyclooxygenase (COX) inhibitory activities of diverse class of flavonoids including hydroxyl and methoxy substituted flavones,(More)
Formation of new blood vessels (angiogenesis) has been demonstrated to be a basic prerequisite for sustainable growth and proliferation of tumor. Several growth factors, cytokines, small peptides and enzymes support tumor growth either independently or in synergy. Decoding the crucial mechanisms of angiogenesis in physiological and pathological state has(More)
Developing antiangiogenic agents using natural products has remained a significant hope in the mainstream of anticancer research. In the present investigation series of flavonoids possessing di-, tri-, tetra-, and penta-hydroxy substitutions were evaluated as antiangiogenic agents using in vivo choriallantoic membrane model. The MTT-based cytotoxicity(More)
Angiogenesis: a process of generation of new blood vessels has been proved to be necessary for sustained tumor growth and cancer progression. Inhibiting angiogenesis pathway has long been remained a significant hope for the development of novel, effective and target orientated antitumor agents arresting the tumor proliferation and metastasis. The process of(More)
Phytotherapy has played an important role in the management of diabetes and related complications. In the present study different fractions of Catharanthus roseus L. (Apocynaceae), Ocimum sanctum L. (Labiatae), Tinospora cordifolia Willd. (Menispermaceae), Aegle marmelos L. (Rutaceae), Ficus golmerata L. (Moraceae), Psoralea corlifolia L. (Fabaceae),(More)
Abstract A series of asymmetric indole curcumin analogs were synthesized and evaluated as possible inhibiters of pro-inflammatory enzymes such as COX-2, pro-inflammatory cytokines as TNF-α and IL-6, trypsin and β-glucuronidase. They were also tested for antioxidant activities. The results showed that compounds 5e and 5h were found to be the most potent(More)
Synthetic derivatives of 1-(2-hydroxy-3-(2-hydroxy-cyclohexyl)-4,6-dimethoxy-phenyl)-methanone were evaluated in-vitro for their activities related to antioxidant and anti-inflammatory. The antioxidant potential was determined by calculating reducing potential, OH and DPPH (2,2-diphenyl-1-picryl hydrazine) radical scavenging activities. The in-vitro(More)
A series of nitrogen-containing benzophenone analogues were synthesized by Mannich reaction and evaluated for the inhibition of pro-inflammatory cytokines, TNF-alpha and IL-6. DPPH (1,1-diphenyl-2-picryl hydrazine) radical scavenging activity and its kinetics were studied to determine the antioxidant potential of the test samples. All the synthesized(More)
A novel series of 3-(substituted)-aryl-5-(9-methyl-3-carbazole)-1H-2-pyrazolines (5a-o) has been synthesized and the structures of newly synthesized compounds were characterized by IR, (1)H NMR and mass spectral analysis. All the synthesized compounds were evaluated for their in vitro and in vivo anti-inflammatory activity, and also for their antioxidant(More)
The water, ethanol and chloroform extracts of selected plants such as Adhatoda vasica (L.) (Acanthaceae), Caesalpinia bonduc (L.), Cassia fistula (L.) (Caesalpiniaceae) and Biophytum sensitivum (L.) (Oxalidaceae) were evaluated for rat lens aldose reductase inhibitory (RLAR) potential, anti-cataract and antioxidant activities. All the samples inhibited the(More)
