ABSTRACT
The aim of this review is to improve the solubilization and bioavailability of poorly soluble drugs by using various approaches like physical, chemical and others modifications or techniques. The solubility of a solute is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature. Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Drug efficacy can be severely limited by poor aqueous solubility and some drugs also show side effects due to their poor solubility. There are many techniques which are used to enhance the aqueous solubility. The ability to increase aqueous solubility can thus be a valuable aid to increasing efficiency and/or reducing side effects for certain drugs. This is true for parenterally, topically and orally administered solutions. Physical modifications techniques like media milling/ nanocrystal technology, cryogenic technology, supercritical fluid process, modification of the crystal habit,complexation, micellar technologies, chemical modifications, other techniques like co-crystallization, cosolvency, hydrotrophy are used for increase the solubility of very soluble drugs like dolargin, loperamide, tubocurarine, doxorubicin, ibuprofen, griseofulvin, diazepam, naproxen, carbamazepine, nifedipine, phytosterol etc.

ABSTRACT:
Quinoxaline derivatives have emerged as an important class of benzoheterocycles because of their diverse pharmacological and biological properties, which make them privileged structures in combinatorial drug discovery libraries. Also Quinoxaline derivatives constitute useful intermediates in organic synthesis. The pharmaco-logical importance of quinoxalines and their utility as building blocks in organic synthesis have directed considerable research activities toward the synthesis of suitably substituted quinoxaline rings. Extensive researches have generated numerous synthetic approaches for the construction of the skeleton of such heterocycles. Quinoxalines are, in general, comparatively easy to prepare, and numerous derivatives have been designed and prepared for potential use as biologically active materials. Oxidation of both nitrogen of the quinoxaline ring dramatically increases the diversity of certain biological properties.
Quinoxalines, including their fused-ring derivatives, display diverse pharmacological activities.A number of synthetic strategies have been developed for the preparation of substituted quinoxalines. The classical synthesis of quinoxalines involves the condensation of an aromatic 1, 2-diamine with a 1, 2-dicarbonyl compound. The reaction is facile and is the most widely used synthetic method for both quinoxaline itself and its derivatives. Despite remarkable efforts,the development of an effective method for the synthesis of quinoxalines is still an important challenge.

Abstract
A neoplasm or tumor is a abnormal mass of tissue, the growth of which exceeds and is uncoordinated with that of the normal tissue and continues in the same manner after cessation of the stimuli which have initiated it.
A malignant tumor grows rapidly and continuously, and even when it has impoverished its host and source of nutrition, still retains the potentiality for further proliferation. Besides, malignanat tumors invade and destroys neighbouring tissues and possess no effective capsule, a malignant tumors readily ulcerate and tend sooner or later dessiminate and form metastases.

ABSTRACT
This article describes the quantitative determination of percentage of drug concentration in pure and in formulated pharmaceutical dosage forms by using RP-HPLC. Procedure does not require prior separation of components from the sample.The mobile phase consists of methanol-water (80:20 v/v) for RP-HPLC with injection volume of 20μl.The RP-HPLC method was developed on a C-8 (150x4.6mm) column with detection carried out by variable wavelength detector at 209nm and 220 nm for ramipril, cardace, odopril respectively…Thus the Rt values obtained for different dosage forms are 1.59,1.44,1.34,1.35…..respectively with the concentration of 100% for pure drug and 97.54%,91.03%,65.76%.......respectively.

Abstract:
The main concept of the study was to find out the penetration of boots ibuprofen gel at different frequencies such as 20 kHz and 40 kHz through cellulose membrane exposed to ultrasound. Different sonicator bath were used for different frequencies. Ultrasound has been used to enhance penetration of ibuprofen from transdermal preparation. Boots ibuprofen gel was used in the experiment. Ibuprofen is a NSAIDs drug which is used to enhance healing effect against inflammation, pain and analgesics.
Frequency, intensities, duty cycle are the important factor. In this experiment frequency variable was used. 20 kHz and 40 kHz frequencies were used in this experiment.Boots ibuprofen gel max (10%) was used to measure the penetration of ibuprofen through the cellulose membrane exposed to ultrasound. By using the Franz diffusion cell penetration of ibuprofen was found out. An amount of ibuprofen permeated through cellulose membrane was found out using High Performance Liquid Chromatography (HPLC).       Penetration of  ibuprofen was found out more lower frequency.  However the penetration ibuprofen also increase compare to control in first hour. The ANOVA result: sample assuming equal variances were performed to find out significance difference (P<0.05) between control and different ultrasound frequencies and also the rate gradients were measured. The P value got for the control and 40 kHz frequency was 0.123, which indicate that there is no significance difference observed for permeation of ibuprofen from gel . P value of control and 20 kHz frequency applying for 2 min was 0.05 which was similar P value, which shows that nearly significance observed between two value. The P value of control and 20 kHz for 5 minute was 0.002 which indicate that there was a significance observed between this two value.   From the result it shows that lower frequency with more time give good penetration result.
