Find the most general Anti derivative {eq}\int sin\theta(cot \theta +csc\theta) d\theta {/eq} Antiderivatives: Taking the antiderivative is acquiring the reverse of the operation of the derivative. This means that we integrate the given function to determine its antiderivative. The result ...
Inuloxin D (4) was converted into the corresponding 4-O-acetyl derivative by usual acetylation (12, Figure 3b). The 1H NMR spectrum of 11 differed from that of 3 by absence of the two doublets due to the protons of the exocyclic methylene group and the presence instead of four doublets...
such as substitution, integration by parts, and trigonometric substitution. They can also combine these techniques when appropriate. The inverse operation of finding the derivative is called “Integration” or “antidifferentia
Crystal structure analysis of 2,3-dideoxy-3-fluorocytidine (1) and its prodrug derivative, N4-dimethylaminomethylene-2,3-dideoxy-3-fluorocytidine (2), active anti-HIV nucleoside analogues, reveals that both structures adopt an anti conformation about the glycosyl bond. The furanose ring is C2-...
Four novel mixed-ligand vanadyl complexes, [VIVO(L2-2H)(L1)], including a bidentate polypyridyl DNA intercalator (L1) and a tridentate salicylaldehyde semicarbazone derivative (L2) as ligands, were synthesized, characterized by a combination of techniques, and evaluated in vitro. Both complexes ...

Introduction Emodin (3-methyl-1,6,8-trihydroxyanthraquinone, Figure 1) is a naturally occurring anthraquinone derivative that is widely distributed in different plants (rhubarb, aloe), lichens and terristrial fungi, that has also been isolated from marine-derived fungi and marine sponge-associated ...

of hydroxyl to carbonyl at C-3 are the usual modifications involved in the formation of lupane derivative (121–132; 206–230). 2,3-seco-lupane triterpene (127) is another remarkable modification found in nature; synthesis of which is proposed by Almeida et al. (2020) via oxidation of a...
