Dihydrocinchonamine is an example of a more complicated molecule which has been prepared by the method (equation 33) 〈78JA589〉. While from a mechanistic point of view the reaction is formally a base-catalyzed cyclizative condensation, the structures involved are certainly not ideal for such ...
Aspirin (chemically acetylsalicylic acid) is the oldest and the most popular example of small-molecule drugs commonly used for pain, fever, and inflammation (Cohen, 2015). In some cancer treatment, small molecular inhibitors specifically targeting to rapidly growing cancerous cells are considered as ...
Q.Give an example of a covalent compound with a formula of A2O Q.Give one example each of the following: (i) A molecule containing a single covalent bond (ii) A molecule containing a double covalent bond (iii) A molecule containing a triple covalent bond ...
THE substance formerly called `β-quinol' and obtained by crystallization of quinol from methanol has been shownto be a compound of three molecules of quinol with one molecule of methanol. It is one of a series of solid compounds of very similar crystalline structure, which consists of two int...
THE substance formerly called `尾-quinol' and obtained by crystallization of quinol from methanol has been shownto be a compound of three molecules of quinol with one molecule of methanol. It is one of a series of solid compounds of very similar crystalline structure, which consists of two ...
而变的水性溶解度:The solubility of acetriptan Form III in aqueous media as a function of pH was measured and is presented in Table 9. The aqueous solubility of acetriptan is low (~0.015 mg/mL) and constant across the physiological pH range due to the lipophilic nature of the molecule....
a) Which structure is aromatic? b) Which structure is anti-aromatic?Which heterocycles are aromatic?Which of the following would NOT be aromatic?Which of the following is aromatic?Define and give an example of an aromatic molecule.Give examples of a polycyclic aromatic compound.Define what is ...
Based on the principles of retrosynthesis, where the target molecule is transformed into simple precur- sors by 'breaking' bonds that can be formed from syn- thetic transformations, 'bio-retrosynthesis' involves the design of an artificial enzyme cascade — a syn- thetic biochemical pathway — ...
Both, oxides and phosphates, are among the most important classes of inorganic compounds. For example, silicon dioxide (SiO2) is the main compound on the earth crust constitution, and apatite, a complex mineral form of calcium phosphate, Ca5(PO4)3 (OH, F, Cl), is the main compound on ...
(DEHP), can disrupt male rat reproductive development and function in a manner similar to antiandrogens. Because DBP and its biologically active metabolite did not bind the androgen receptorin vitro, it is an example of an environmental antiandrogen that disrupts androgen-regulated male sexual ...
