Irbesartan is an angiotensin II receptor inhibitor, angiotensin II receptors are divided into AT1, AT2. Irbesartan by selectively blocking the AT1 receptor of AnglII, it can inhibit the conversion of AngI into AngII, and can specifically antagonize the ACE 1 receptor (AT1). Irbesartan's antagonistic effect on AT1 is 8500 times that of AT2, which inhibits vasoconstriction and the release of aldosterone by selectively blocking AngII's binding to AT1 receptors, resulting in a hypotensive effect.
Guanidine thiocyanate is white crystalline, melting point 116~121 °C, at 20 °C, the PH value of 6mol/L in water is 4.5~6, and the solubility is completely dissolved. It is a kind of decoupling agent, is a strong class of protein denaturant, can dissolve protein, make the protein secondary structure disappear, cell structure degradation, nucleoprotein rapid separation from nucleic acid. For denaturing lysed cells; RNA and DNA were extracted without RNA enzyme and DNA enzyme activity.
Guanidine thiocyanate is mainly used in biomedicine, chemical reagents, etc.

Fluralaner works mainly by interfering with GABA-gated chloride channels, similar to the targets of insecticides such as cyclopentadienes, phenylpyrazoles and macrolides.
Fluralaner is a broad-spectrum pesticide with good insecticidal activity against pests such as ticks, fleas, lice, hemiptera, and diptera. It is more virulent than or comparable to commonly used pesticides.

Fipronil mainly induces Cl- flow by blocking the Cl-channel of the nerve membrane controlled by γ-aminobutyric acid receptors, causing extreme excitement of the nervous system and causing the death of the worm, achieving the control effect of a variety of economic pests.
Fipronil has the advantages of broad-spectrum and high efficiency. It has been widely used in many agricultural fields and is a commonly used pesticide for pest control.
Fipronil is mainly used in crops such as rice, sugar cane, potatoes, etc., and animal health is mainly used to kill parasites such as fleas and lice on cats and dogs.

Finasteride is an essential drug for the treatment of prostatic hyperplasia and prostatitis in China. Its effect is characterized by the selective blocking of androgen stimulation of the prostate, but rarely affects the sexual function of men.
Finasteride is a resistant hormone drug, which can selectively inhibit 5α-reductase, so that the process of converting testosterone into 5α-dihydrotestosterone (DHT) is blocked, the level of male hormones in prostate cells decreases, the prostate-specific antigen in serum decreases, the enlarged prostate volume decreases, and the urine flow rate increases, thereby reducing the patient's symptoms and achieving the purpose of treating prostatic hyperplasia.

Ferrous sulfate is a light blue-green monoclinic crystal with a density of 1.898g/cm3 and melted in crystal water at 64 °C. Soluble in water, the aqueous solution is acidic. It gradually weathers in the air and is oxidized to a yellow-brown alkaline iron salt. At 300 °C, all crystal water is lost, and the anhydrous substance is a white powder.
Ferrous sulfate is used medicinally as a local astringent and blood tonic. It is also used as a nutritional supplement such as iron enhancer and fruit and vegetable coloring agent.

Ferrous fumarate is a safe and efficient organic nutrient iron supplement that belongs to organic iron. After ferrous fumarate is absorbed, divalent iron ions are easier to decompose, entering red blood cells without additional energy, not stimulating the stomach and intestines, can improve and maintain the normal level of heme, can be used as a nutritional additive for a long time, and is clinically used for the treatment of iron deficiency anemia.
Ferrous fumarate is absorbed in animals in the form of ferrous ions in the duodenum and upper jejunum. Most of the absorbed iron is involved in the synthesis of hemoglobin in the bone marrow, and the remaining part is stored in the reticuloendothelial cells of the bone marrow, liver and spleen in the form of ferritin and hemosiderin, and some is present in the cells of the intestinal mucosa. This absorption method is different from inorganic iron supplements (ferrous sulfate, ferrous carbonate and iron oxide, etc.), it can alleviate the competitive antagonism between trace elements, will not destroy vitamins, will not catalyze oxidation reaction, and has good compatibility with various nutrients, can smoothly pass through the body's absorption barrier, not only greatly improve the absorption and utilization rate of iron, but also improve the absorption rate of other elements. Iron is excreted mainly in the intestines and skin, and small amounts in urine and sweat glands. Most iron is reused when the hemoglobin molecule is released after it is destroyed.
