A series of 3-(4-acetyl-5H-5-phenyl-4,5-dihydro-1,3,4-oxadiazol-2-yl)- 2H-chromen-2-one derivatives were synthesized and evaluated for their anticonvulsant and antioxidant activities. Initially Ethyl-2-oxo-2H-chromene-3-carboxylate was prepared by reacting Salicylaldehyde with Diethyl malonate in presence of piperidine. This compound was treated with hydrazine hydrate to give aromatic hydrazides. Those hydrazides were refluxed with different aldehydes to form arylidines, which were then treated with acetic anhydride to form 3-(4-acetyl-5H-5-phenyl-4,5-dihydro-1,3,4-oxadiazol-2-yl)- 2H-chromen-2-one derivatives. The structures of synthesized compounds were characterized and confirmed by IR and 1HNMR and then screened for antioxidant activity by DPPH reduction method and anticonvulsant activity by MES method. The investigation revealed that out of eight newly synthesized derivatives five were found to possess significant anticonvulsant activity but none of the derivative was found with antioxidant activity.

With the introduction of combinatorial chemistry and high throughput screening, the properties of new chemical entities shifted towards higher molecular weight and increasing lipophilicity that results in decreasing aqueous solubility. It is not surprising that many drug candidates have poor water solubility since the initial selection of drug candidates are based on activity alone. Other physiochemical and biopharmaceutical properties such as permeability, biopharmaceutics and metabolism are rarely considered during the selection process. The aim of this study was to increase dissolution rate of felodipine poorly soluble drugs from BCS class II by complexation process. Complexation was prepared using β cyclodextrine. Different techniques were employed for preparation of complexation with β cyclodextrin like physical mixture, cogrinding, kneading technology, solvent coevaporation.The physical properties of the prepared solid mass of felodipine was characterized by in vitro dissolution studies, UV- spectroscopy, Fourior transform infrared spectroscopy, differential scanning calorimetry (DSC) and  X-ray powder differaction spectroscopy. Additionaly, phase solubility studies were performed to support the in vitro dissolution study. The results of Fourior transform infrared spectroscopy shows the compatibility of drug with cyclodextrin, while differential scanning calorimetry (DSC) and X-ray powder differaction spectroscopy showed the confirmation of complexation of β cyclodextrin with felodipine.

Tissue culture
(often called micropropagation) is a special type of asexual propagation where a very small piece of tissue (shoot apex, leaf section, or even an individual cell) is excised (cut-out) and placed in sterile (aseptic) culture in a test tube, petri-dish or tissue culture container containing a special culture medium.Several industries and nurseries have standardized protocols for the multiplication of ornamentals like orchids genera, carnation, roses, chrysanthemum and plantation crop like banana and cardamom..The compounds responsible for the memory enhancing effects of Bacopa monniera are triterpenoid saponins called bacosides .In the Ayurvedic Materia Medica, Bacopa has been recognized for its brain enhancement characteristics. Bacopa monnieri, a member of the Scrophulariaceae family, is a small, creeping herb with numerous branches, small oblong leaves and light purple flowers. In India and the tropics it grows naturally in wet soil, shallow water and marches. Brahmi (Bacopa monnieri) (Linn) familyScrophulariaceaeis also known as Madhyarasayana in Ayurveda as it increase mental-clarityand brain stimulating action It also possesses anti-inflammatory, analgesic, antipyretic, epilepsy, insanity, anticancer and antioxidant activities, saponins such as bacosides A, B, C and D which are the active triterpenoid principles and known as "memory chemicals".Only  a  very limited research has been  carried  out  on the plant,  under  the present study  assumes singular  significance and it is supposed to contribute a great deal to the existing literature. The present paper highlights the morphogenic response of various auxins and cytokinins on Bacopa monniera.
