Phenylbiguanide (PBG) is a 5-HT3 agonist used to study the role of 5-HT3 receptors in the central nervous system. [1] It has been found to trigger dopamine release in the nucleus accumbens of rats. [2]
Biguanide (/ b aɪ ˈ ɡ w ɒ n aɪ d /) is the organic compound with the formula HN(C(NH)NH 2) 2. It is a colorless solid that dissolves in water to give a highly basic solution. It is a colorless solid that dissolves in water to give a highly basic solution.
There is no more than 1 sigma bond between any two atoms. Molecules with rings have additional sigma bonds, such as benzene rings, which have 6 C−C sigma bonds within the ring for 6 carbon atoms. The anthracene molecule, C 14 H 10, has three rings so that the rule gives the number of sigma bonds as 24 + 3 − 1 = 26. In this case there are 16 ...
In organic chemistry, the phenyl group, or phenyl ring, is a cyclic group of atoms with the formula C 6 H 5, and is often represented by the symbol Ph (archaically φ) or Ø. The phenyl group is closely related to benzene and can be viewed as a benzene ring, minus a hydrogen, which may be replaced by some other element or compound to serve as a ...
The general structure of a guanidine. Guanidines are a group of organic compounds sharing a common functional group with the general structure (R 1 R 2 N)(R 3 R 4 N)C=N−R 5. The central bond within this group is that of an imine, and the group is related structurally to amidines and ureas.
For hydrocarbons, the DBE (or IHD) tells us the number of rings and/or extra bonds in a non-saturated structure, which equals the number of hydrogen pairs that are required to make the structure saturated, simply because joining two elements to form a ring or adding one extra bond (e.g., a single bond changed to a double bond) in a structure reduces the need for two H's.
Succinimide is an organic compound with the formula (CH 2) 2 (CO) 2 NH. This white solid is used in a variety of organic syntheses, as well as in some industrial silver plating processes. The compound is classified as a cyclic imide. It may be prepared by thermal decomposition of ammonium succinate. [4]
Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH) 2 where Ph is the phenyl group C 6 H 5 - and B(OH) 2 is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis.
