Zidovudine (ZDV), also known as azidothymidine (AZT), was the first antiretroviral medication used to prevent and treat HIV/AIDS. It is generally recommended for use in combination with other antiretrovirals. It may be used to prevent mother-to-child spread during birth or after a needlestick injury or other potential exposure. It is sold both by itself and together as lamivudine/zidovudine and abacavir/lamivudine/zidovudine. It can be used by mouth or by slow injection into a vein.

Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. It is an isomer of another solvent, butanone.

Pilocarpine is a lactone alkaloid originally extracted from plants of the Pilocarpus genus. It is used as a medication to reduce pressure inside the eye and treat dry mouth. As an eye drop it is used to manage angle closure glaucoma until surgery can be performed, ocular hypertension, primary open angle glaucoma, and to constrict the pupil after dilation. However, due to its side effects, it is no longer typically used for long-term management. Onset of effects with the drops is typically within an hour and lasts for up to a day. By mouth it is used for dry mouth as a result of Sjögren's disea

Glucuronolactone or Glucurolactone (INN) is a naturally occurring substance that is an important structural component of nearly all connective tissues. It is sometimes used in energy drinks. Unfounded claims that glucuronolactone can be used to reduce "brain fog" are based on research conducted on energy drinks that contain other active ingredients that have been shown to improve cognitive function, such as caffeine. Glucuronolactone is also found in many plant gums.

class of chemical compounds

Queuosine is a modified nucleoside that is present in certain tRNAs in bacteria and eukaryotes. It contains the nucleobase queuine. Originally identified in E. coli, queuosine was found to occupy the first anticodon position of tRNAs for histidine, aspartic acid, asparagine and tyrosine. The first anticodon position pairs with the third "wobble" position in codons, and queuosine improves accuracy of translation compared to guanosine. Synthesis of queuosine begins with GTP. In bacteria, three structurally unrelated classes of riboswitch are known to regulate genes that are involved in the synth

2,2,5,5-tetramethyltetrahydrofuran (TMTHF) or 2,2,5,5-tetramethyloxolane (TMO) is a heterocyclic compound with the formula , or (CH3)2(C(CH2)2OC)(CH3)2. It can be seen as derivative of tetrahydrofuran (oxolane) with four methyl groups replacing four hydrogen atoms on each of the carbon atoms in the ring that are adjacent to the oxygen. The absence of hydrogen atoms adjacent to the oxygen means that TMTHF (TMO) does not form peroxides, unlike other common ethers such as tetrahydrofuran, diethyl ether and CPME.
