1). Pharmacological action of most of
the anti inflammatory activity is either based on inhibition of lysosomal membrane.19 Hence it can be assume that EIA may possibly be acting either by inhibiting the lysosomal enzyme or by stabilizing the membrane. The ESR count has been used for staging the inflammatory disease.20 In order to find out the response of both extracts of I. aspalathoides against inflammation, ESR counting was done. The results were given in Table 2. The result showed selleck chemicals llc that both EIA have the ability to reduce (p < 0.05) the elevated levels of ESR to normal levels at the stage of inflammation. Identification of bioactive principles from medicinal plants is crucial for the standardization of herbal drugs. High Performance Liquid Chromatography is widely employed for screening the phytoconstituents for the quality management of herbal medicines.
HPLC analysis was carried out for EIA and found five different bioactive principles with retention time of 2.828, 3.120, 3.393, 37.292, 49.707 respectively (Fig. 2 and Table 3). The identified compounds selleckchem were expected to belong to the family of pterocarpan which are the major active compounds in I. aspalathoides. It was supported by the previous finding that indigocarpan and mucronulatol, isolated from I. aspalathoides has high anti inflammatory activity. 21 The further research will be performed to identify the specific compounds by preparative HPLC. The present study strongly justified that the stem of I. aspalathoides possess significant anti inflammatory activity. However, further studies focusing on the purification of bioactive compounds and their pharmacological crotamiton action are required for developing effective anti inflammatory drug from I. aspalathoides. All authors have none to declare. The authors are grateful to NRCBS-MKU for providing HPLC analysis facility & DST-PURSE for financial support and Mr. A.P. Selvarajan, Secretary, Sri Kaliswari College, Sivakasi to providing all facilities for my research. “
“Derivatives of sulfamides have attracted interest in recent years as both acyclic
and cyclic compounds exhibit a broad spectrum of physiological activities.1, 1a and 1b 1,2,5-thiadiazolidin-3-one 1,1-dioxide derivatives exhibits antispasmodic activity,2 and are also proposed for the treatment of rheumatoid arthritis.3 Various 1,2,5-thiadiazolidine 1,1-dioxides analogues containing an indole substituent at position two are used for the treatment of migraines,4 and also inhibit human leucocyte elastase enzyme and cathepsin G.5 Various 2,1,3-thiadiazine 2,2-dioxides analogues are reported to act as myorelaxants.6 Aryl-substituted seven- and eight-membered cyclic sulfamides inhibit HIV-1 protease.7 and 8 Sulfamides derivatives are also used in various application in photography,9 as fungicide,10 insecticide,11 & detergents.12 Some 1,2,6-thiadiazine 1,1-dioxides are reported as potent fungicide.
