optimization of the reaction conditions and to show the generality of the method we used the optimized conditions for the synthesis of different types of 12-aryl-tetrahydrobenzo[α]xanthene-11-ones by using of β-naphthol (4, 1.0 mmol), aromatic aldehydes derivatives (5, 1.0 mmol) and dimedone (6, 1.0 mmol). The reaction is fairly general, clean, rapid, and efficient. The experimental procedure is very simple…

7th November, 2014 Efficacy and safety comparisons between collagen derivatives and glucosamine sulfate supplements in treating adults with knee osteoarthritis. Linh Nguyen (11916828). Evidence based practice. University of Technology, Sydney I. CLINICAL SCENARIO During my clinical placement, I have come across a scenario where a 40 year old woman came into the pharmacy, saying that she had recently diagnosed with knee osteoarthritis (KOA) and was looking for a good dietary supplement as…

promotes its brand in its every animated film released, every derivative sold, every new playing channel and sales channel as well as every tourist entering into Disneyland. By virtue of these brand promotions, Disney can increase brand loyalty without any cost while gaining more profits. Disney Group’s value chain mainly consists of four parts: film and television, media network, Disneyland and derivatives. Disney mainly relies on derivatives and Disneyland which account for over 80% in…

The claim that “without application in the world, the value of knowledge is greatly diminished” implies that some knowledge is more valuable than others. More specifically, shared knowledge is more respected than personal knowledge. In other words, if you don’t use or share what you know/learn in real life, the knowledge loses validity and worth. The areas of knowledge Mathematics and the Arts will be used in this essay to investigate this claim with respect to ways of knowing of Reason and…

natural conditions in almost all parts of the world wherever wheat is cultivated. • Genotype specificity: Both the plant species viz. maize and I. cylindrica are genotype non-specific for hybridization with any variety of wheat, triticale or their derivatives, proving their suoeriorty over anther culture system. • Availability of pollen: Likewise maize, pollen of I. cylindrica is readily available in abundance during the wheat hybridization…

Derivatives e.g swaps and futures are mainly used to assist CAO (China Aviation Oil) in enhancing their procurement proficiency and hedging tool in the beginning to reduce the risk in their daily trading activities. Eventually derivatives are used in speculative trading without having a proper risk management environment in place in hope to gain more profit from the positive market movement. When the trading was done at the start, Mr Chen Juilin the managing director and CEO of the company, was…

biologically active compounds that attracted a great deal of interest in the medicinal chemistry due to their potent biological activities and wide range of pharmaceutical applications [1-6]. Several publications recorded that some of benzosuberone derivatives possess antipyretic, anti-inflammatory, antimicrobial, antiulcer and antitumor activities [1-6]. As an indication for the importance of the benzosuberone based compounds, more than 100 registered patents and hundreds of publications on…

been designed to synthesize more and more novel lead molecules possessing least toxicity with highest efficacy.Schiff bases have importance since the last decade that it pulled the researchers towards the most appropriate access in forming novel derivatives in medicinal field.(Anu et al, 3013). Due…

halohydrins to give the corresponding addition products (Shabarova and Bogdanov, 1994). Selected examples of the side reactions that occur during oligonucleotide synthesis are given below. Tri-O-acetyluridine (S.1) reacts with MSNT to produce the triazolo derivative S.2 (Figure 2.1.2; Reese and Ubasawa, 1980). During deprotection with ammonium hydroxide, S.2 gives cytidine (S.3). Interestingly, during deprotection with either the tetramethylguanidinium…

The heterocyclic compounds naming tetrahydrocarbazoles having the significant biological properties. The newly substituted tetrahydrocarbazole derivatives were prepared from substituted phenylhydrazine and cyclohexanone in glacial acetic acid under reflux. These intermediates on reaction with substituted aromatic acid chlorides in alkaline media finally converted to N-Substituted tetrahydrocarbazoles. Fifteen compounds are synthesized and charaterized by their melting point (MP), IR, NMR, MS…
