This is a list of 5α-reductase inhibitors (5α-RIs), drugs which inhibit one or more isoforms of the enzyme 5α-reductase.This enzyme is responsible for the conversion of the androgen hormone testosterone into the more potent dihydrotestosterone (DHT) and is essential for the production of neurosteroids like allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol from ...
5α-Reductase inhibitors (5-ARIs), also known as dihydrotestosterone (DHT) blockers, are a class of medications with antiandrogenic effects which are used primarily in the treatment of enlarged prostate and scalp hair loss. They are also sometimes used to treat excess hair growth in women and as a component of hormone therapy for transgender ...
RFC Boxes [1-8] are the amino acid sequences found in human replication factor C. RFC 1 is the largest RFC subunit, with 8RFC Boxes. Other RFC subunits also have 7 RFC boxes. RFC box 1 has a 90 amino acid-long region, while RFC box 2 is a highly conserved subunit. RFC box 3 includes a phosphate-binding loop.
TrimSpa was a dietary supplement designed for weight loss, marketed by the company Goen Technologies and headed by Alexander Szynalski. [1] The ephedra-based supplement was marketed by TrimSpa to help "stave off hunger", [2] until ephedra was banned from the United States. TrimSpa's parent company, Goen Technologies, filed for bankruptcy ...
IC 50 values are typically expressed as molar concentration. IC 50 is commonly used as a measure of antagonist drug potency in pharmacological research. IC 50 is comparable to other measures of potency, such as EC 50 for excitatory drugs. EC 50 represents the dose or plasma concentration required for obtaining 50% of a maximum effect in vivo. [1]
The enzyme unit, or international unit for enzyme (symbol U, sometimes also IU) is a unit of enzyme's catalytic activity. [ 1 ] 1 U (μmol/min) is defined as the amount of the enzyme that catalyzes the conversion of one micro mole of substrate per minute under the specified conditions of the assay method .
EC 50 is a measure of concentration, expressed in molar units (M), where 1 M is equivalent to 1 mol/L. The EC 50 of a graded dose response curve therefore represents the concentration of a compound where 50% of its maximal effect is observed. [4] The EC 50 of a quantal dose response curve represents the concentration of a compound where 50% of ...
Toxic units (TU) are used in the field of toxicology to quantify the interactions of toxicants in binary mixtures of chemicals. [1] A toxic unit for a given compound is based on the concentration at which there is a 50% effect (ex. EC50) for a certain biological endpoint. One toxic unit is equal to the EC50 for a given endpoint for a specific ...
