Marjoram is a perennial herb in the mint family that grows wild in the Mediterranean region. It is used primarily as seasoning in cooked dishes but is also found in beauty and health care products. Often mistaken for oregano, marjoram is frequently called by many different names, including sweet marjoram, knotted marjoram, joy of the mountains, and wintersweet.
The structure of paclitaxel, a widely used mitotic inhibitor. A mitotic inhibitor is a drug that inhibits mitosis, or cell division. These drugs disrupt microtubules, which are structures that pull the cell apart when it divides. Mitotic inhibitors are used in cancer treatment, because cancer cells are able to grow and eventually spread through the body (metastasize) through continuous mitotic division.
Competitive inhibition. Competitive inhibition is a form of enzyme inhibition where binding of the inhibitor to the active site on the enzyme prevents binding of the substrate and vice versa. Most competitive inhibitors function by binding reversibly to the active site of the enzyme. competitive inhibitor could bind to an allosteric site of the free enzyme and prevent substrate binding, as long as it does not bind to the allosteric site when the substrate is bound. For example, strychnine acts as an allosteric inhibitor of the glycine receptor in the mammalian spinal cord and brain stem.
