In homogeneous catalysis, catalysts are in the same phase as the reactants. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.99-67-2, Name is 2-Allylpent-4-enoic acid, SMILES is C=CCC(CC=C)C(O)=O, belongs to quinuclidine compound. In a document, author is Sonar, Vijayakumar N., introduce the new discover, Application In Synthesis of 2-Allylpent-4-enoic acid.
Novel substituted (Z)-2-(N-benzylindol-3-ylmethylene)-quinuclidin-3-one and (Z)-(+/-)-2-(N-benzylindol-3-ylmethylene)-quinuclidin-3-ol derivatives as potent thermal sensitizing agents
Use of ionizing radiation is essential for the management of many human cancers, and therapeutic hyperthermia has been identified as a potent radio sensitizer. Radiation therapy combined with adjuvant hyperthermia represents a potential too] to provide outstanding local-regional control for refractory disease. (Z)-(+/-)-2-(N-Benzylindol-3-ylmethylene)quinuclidin-3-oI (2) and (Z)-(+/-)-2-(N-benzenesulfonylindol-3-ylmethylene)quinuclidin-3-ol (4) were initially identified as potent thermal sensitizers that could lower the threshold needed for thermal sensitivity to radiation treatment. To define the structural requirements of the molecule that are essential for thermal sensitization, we have synthesized and evaluated a series of (Z)-2-(N-benzylindol-3-ylmethylene)quinuclidin-3-one (9), and (Z)-()-2-(N-benzylindol-3-ylmethylene)quinuclidin-3-oI (10) analogs that incorporate a variety of substituents in both the indole and N-benzyl moieties. These systematic structure-activity relationship (SAR) studies were designed to further the development and optimization of potential clinically useful thermal sensitizing agents. The most potent analog was compound 10 (R-1 = H, R 2 = 4-Cl), which potently inhibited (93% inhibition at 50 mu M) the growth of HT-29 cells after a 41 degrees C/2 h exposure. (c) 2007 Elsevier Ltd.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.If you’re interested in learning more about 99-67-2.
