Eplerenone is an antimineralocorticoid, or an antagonist of the mineralocorticoid receptor (MR). [21] Eplerenone is also known chemically as 9,11α-epoxy-7α-methoxycarbonyl-3-oxo-17α-pregn-4-ene-21,17-carbolactone and "was derived from spironolactone by the introduction of a 9α,11α-epoxy bridge and by substitution of the 17α-thoacetyl ...
The molecular formula C 24 H 30 O 6 may refer to: Eplerenone , a steroidal antimineralocorticoid of the spirolactone group Estriol triacetate , an estrogen medication and an estrogen ester
Eplerenone is a newer drug that was developed as a spironolactone analog with reduced adverse effects. In addition to the y-lactone ring and the substituent on C-7, eplerenone has a 9α,11α-epoxy group. This group is believed to be the reason why eplerenone has a 20-40-fold lower affinity for the mineralocorticoid receptor than spironolactone. [7]
Potassium-sparing diuretics act to prevent sodium reabsorption in the collecting tubule by either binding ENaCs (amiloride, triamterene) or by inhibiting aldosterone receptors (spironolactone, eplerenone). This prevents excessive excretion of K + in urine and decreased retention of water, preventing hypokalemia. [10]
Because almost all water bodies are dynamic in their composition, the relevant quality parameters are typically expressed as a range of expected concentrations. They include the natural and man-made chemical , biological and microbiological characteristics of rivers , lakes and ground-waters , the ways they are measured and the ways that they ...
In 1999, the Water Quality Advisory Board was created by Executive Order 1999-10. This body is responsible for advising the DEQ on the "implementation of a comprehensive, long-term water quality monitoring program designed to measure the quality of Michigan's streams, rivers and lakes, and detect areas of the state that need additional water ...
The biological monitoring working party (BMWP) is a procedure for measuring water quality using families of macroinvertebrates as biological indicators. [ 1 ] The method is based on the principle that different aquatic invertebrates have different tolerances to pollutants .
Within the CEN, standards are drafted by Technical Committees (TCs) [2] of particular scope on the basis of national participation by the CEN members, i.e. the National Standardization Bodies of the European Union member states and some additional European country. [3] The following Technical Committees exist or existed within CEN: [4]
