In recent decades, a variety of pharmaceutical research has been conducted to develop new dosage forms. Fast dissolving tablets are one of the fruitful results of these researches. Fast dissolving tablets disintegrate and/or dissolve rapidly in the saliva without chewing and additional water. Mouth dissolving tablets have been formulated for pediatric, geriatric, and bedridden patients and for active patients who are busy and travelling and may not have access to water. This review includes advantages, disadvantages, desired characteristics and various methods used for formulation of fast dissolving...

Dihydrofolate reductase (DHFR) was discovered in the late 1950s by investigators searching for folate-dependent enzymes involved in 1-carbon metabolism, with its already known application as anti-cancer and as antibiotics. This study focuses on structure of Dihydrofolate, its interaction with specific amino acids, mechanism of DHFR catalysis. The reason of study was to focus on compounds which can inhibit DHFR and has applications as antifungal agents, antimalarial agents, ant tuberculosis agents, for Leishmaniasis and Trypanosomiasis treatment. Also, to find out the reason of resistance to antifolates and ways to overcome them, recent drugs under each class of agents and drugs under clinical...

Biosensors have revolutionized the way of diagnosis by allowing detection of diseases at earlier stage & detection of altered amount of biomarkers in the body. All biosensors usually involve minimal sample preparation as the biological sensing component is highly selective for the analyte concerned. There are numerous biosensors available now-a-days such as electrochemical biosensors, optical biosensors, DNA biosensors, microbial biosensors, mass based biosensors, calorimetric biosensors etc, which enable reliable & fast detection of analyte & provide accurate results at earliest. Biosensors have many uses in clinical analysis, general health care monitoring, veterinary and agricultural applications, industrial processing and monitoring, and environmental pollution control. Biosensor technology has the potential to provide fast and accurate detection, reliable imaging of cancer cells, and monitoring of angiogenesis and cancer metastasis, and the ability to determine the effectiveness of anticancer chemotherapy...

Combinatorial chemistry is a new methodology by which we can simultaneously synthesize a number of possible compounds that could produce simultaneously a very large number of compounds, called libraries.Combinatorial chemistry involves the rapid synthesis or the computer simulation of a large number of different but often structurally related molecules or materials. Combinatorial chemistry is especially common in CADD (Computer aided drug design) and can be done online with web based software, such as Molinspiration.In the past, chemists have traditionally made one compound at a time. For example compound A would have been reacted with compound B to give product AB, which would have been isolated after reaction work up and purification through crystallization, distillation, or chromatography. In contrast to this approach, combinatorial chemistry offers the potential to make every combination of compound A1 to Am with compound B1 to Bn. Although combinatorial chemistry has only really been taken up by industry since the 1990s, its roots can be seen as far back as the 1960s when a researcher at...
