In a recent article I discussed a nomenclature for compounds containing polyatomic ions (and ions with more than one atom) and how this nomenclature could be helpful in determining which compounds may be useful as medicines, without having to rely on the properties of compounds. In addition to containing polyatomic ions, compounds containing these ions are commonly referred to as “p-ionics” because they contain one or more p-ions.
Since so many new and exciting compounds have been discovered recently, a useful set of names was needed to describe compounds containing polyatomic ions. Therefore, the concept of a naming worksheet was born, to provide a generic name for compounds containing p-ions. Here is a short description of how a naming worksheet works, based on the compound ion shown above.
A name is given to each new compound by aggregating the known properties of the compound with the known properties of compounds of known names. That is, the sum of the known properties of the new compound and those of its immediate predecessors is referred to as the nomenclature. The initial three letters of the compound’s scientific name are placed at the beginning of the nomenclature. In general, compounds containing p-ions are named using the term “p-ion”.
In recent publications on name usage, such terminology is used to describe compounds containing different types of ions. For example, a compound is called “methylamine” when it contains the four ions mentioned in the name.
The next step is to determine which individual atoms make up the compound. By doing this, it becomes easier to determine the compounds’ names, since all four atoms must be identified in order to create a valid compound. This does not necessarily imply that it will be easier to come up with names for compounds containing less common atoms. To do this, look for bonds and/or electrons in the compound’s atoms. Then, assign each of these to the appropriate words. After doing this, assign each of the names to the corresponding atoms in the compound, one by one.
Now you have the names for the compounds and can determine which compound should be named “naming”, given that the compound ion in question has an active part that is another compound containing p-ions. Note that if there are no “antiprotonic” ions in the compound, then you don’t have to worry about the names of the compounds containing these ions. In these cases, it will always be appropriate to use the term “antiprotonic ion”. However, the compounds containing these ions may still be named as “naming compounds”.
Once you have the names for the compounds, your next step is to find compounds containing these ions that are currently being investigated for medical uses. You can browse these compounds using the search feature on the Internet Molecular Biology Database (IMB) website, which is maintained by the American Society for Mass Spectrometry (ASM).
