Application

3-Indoleacetic acid (IAA) can be used as a building block to synthesize ,(±) harmacine using 4,4-diethoxybutan-1-amine via an acid-catalyzed acyl iminium ion cyclization reaction.
(±)-Harmacine is a vital step in the synthesis of a variety of indole alkaloids and dopamine/serotonin receptor ligands. IAA can also be used in the preparation of alkaloid (±)-19-hydroxyibogamine.

Alteration of the lipid composition of biological membranes interferes with their function and can cause tissue damage by triggering apoptosis. Upon lipid bilayer stress, the endoplasmic reticulum mounts a stress response similar to the unfolded protein response. However, only a

Algal blooms can seriously affect the operation of water treatment processes including low pressure (micro- and ultra-filtration) and high pressure (nanofiltration and reverse osmosis) membranes mainly due to accumulation of algal-derived organic matter (AOM). In this study, the different components

Topoisomerase II (TOP2) relieves torsional stress by forming transient cleavage complex intermediates (TOP2ccs) that contain TOP2-linked DNA breaks (DSBs). While TOP2ccs are normally reversible, they can be "trapped" by chemotherapeutic drugs such as etoposide and subsequently converted into irreversible TOP2-linked
