The quantitative structure-activity relationships (QSAR) of the Aldose Reductase (AR) inhibitory activity of 48 flavones were studied using Free-Wilson, Combinatorial Protocol in Multiple Linear Regression (CP-MLR), and Partial Least Squares (PLS) procedures. For the latter two procedures 152 Molconn-Z parameters and six indicators corresponding to the(More)
Two series of closely related antimalarial agents, 7-chloro-4-(3',5'-disubstituted anilino)quinolines, have been analyzed using Combinatorial Protocol in Multiple Linear Regression (CP-MLR) for the structure-activity relations with more than 450 topological descriptors for each set. The study clearly suggested that 3'- and 5'-substituents of the anilino(More)
BACKGROUND The combretastatins are a class of natural stilbenoids. These molecules generally share three common structural features: a trimethoxy "A"-ring, a "B"-ring containing substituent often at C3' and C4', and an ethene bridge between the two rings, which provides necessary structural rigidity. Members of the combretastatin family possess varying(More)
This study is based on the synthesis of a series of combretastatin analogs with different substitutions on one aryl moiety and a carboxylic group in connecting chain. Cis-configuration with respect to aryl groups was established by X-ray crystal analysis. All the synthesized compounds were evaluated for anticancer activity against a panel of cell lines. Six(More)
The chemical structure indices have a significant role in providing direction to the design of chemotherapeutic agents. These indices come from the experimental domain as well as through the computations. While the experimental properties of compounds have practical value, the indices from computational domain offer fast and economic inputs to simulations.(More)
A series of 4-aryl/heteroaryl-4H-fused pyrans was synthesized via multicomponent reaction in a microwave synthesizer. All the pyrans were evaluated for in vitro xanthine oxidase inhibition. Structure–activity relationship was also established. Among the series of 108 compounds, Compound 5n was the most potent displaying remarkable inhibition against the(More)
Parathyroid carcinoma is a very rare cause of hyperparathyroidism. The diagnosis is usually established on histopathological grounds of capsular and vascular invasion, but a potential clue to the diagnosis is also offered by the severity of clinical profile, abrupt onset of symptoms, and a high degree of hypercalcemia and raised serum parathyroid hormone(More)
A QSAR study has been carried out on antimalarial activity and cytotoxicity of substituted 4-aminoquinolines using topological and structure descriptors from DRAGON software. The descriptors, relevant to each activity, were identified by Combinatorial Protocol in Multiple Linear Regression (CP-MLR) approach. The different descriptors were identified for the(More)
The antitubercular activity of ortho-, meta- and para-substituted biphenyl analogs of 2-nitroimidazo[2,1-b][1,3]oxazine has been analyzed through combinatorial protocol in multiple linear regression using physicochemical and structural descriptors obtained from MOE software. The different electronic, hydrophobic, and steric descriptors have been identified(More)
A high dimensional QSAR study on the Aldose Reductase inhibitory activity of some flavonoids: Topological descriptors in modeling the activity The inhibition of Aldose Reductase (AR) in polyol pathway may prevent and address the cure of the complications such as cataract, neuropathy and retinopathy arising out of the diabetes mellitus. A number of(More)
