The chemical reactions and pathways resulting in the formation of isoquinoline alkaloids, alkaloid compounds that contain bicyclic N-containing aromatic rings and are derived from a 3,4-dihydroxytyramine (dopamine) precursor that undergoes a Schiff base addition with aldehydes of different origin. The chemical reactions and pathways involving various organic and inorganic nitrogenous compounds; includes nitrogen fixation, nitrification, denitrification, assimilatory/dissimilatory nitrate reduction and the interconversion of nitrogenous organic matter and ammonium. The chemical reactions and pathways resulting in the formation of terpenoid indole alkaloids, compounds formed from the condensation of tryptamine (derived from tryptophan) and secologanin (derived from geranyl pyrophosphate). The chemical reactions and pathways resulting in many of the chemical changes of compounds that are not necessarily required for growth and maintenance of cells, and are often unique to a taxon. In multicellular organisms secondary metabolism is generally carried out in specific cell types, and may be useful for the organism as a whole. In unicellular organisms, secondary metabolism is often used for the production of antibiotics or for the utilization and acquisition of unusual nutrients. The chemical reactions and pathways resulting in the formation of organic and inorganic nitrogenous compounds. The chemical reactions and pathways resulting in the formation of nicotine, (S)(-)-3-(1-methyl-2-pyrrolidinyl)pyridine. The chemical reactions and pathways resulting in the formation of dethiobiotin, a derivative of biotin in which the sulfur atom has been replaced by two hydrogen atoms. The chemical reactions and pathways resulting in the formation of paclitaxel, an alkaloid compound used as an anticancer treatment. The chemical reactions and pathways resulting in the formation of epothilone, a drug obtained from the myxobacteria Sporangium cellulosum that interferes with cell division. Some epothilones are being studied as treatments for cancer. The chemical reactions and pathways resulting in the formation of dipyrrins (pyrromethanes), compounds containing two pyrrole rings linked through a methine, -CH=, group. The chemical reactions and pathways involving various organic and inorganic nitrogenous compounds, as carried out by individual cells. The chemical reactions and pathways involving alkaloids, nitrogen containing natural products which are not otherwise classified as peptides, nonprotein amino acids, amines, cyanogenic glycosides, glucosinolates, cofactors, phytohormones or primary metabolites (such as purine or pyrimidine bases). The chemical reactions and pathways resulting in the formation of alkaloids, nitrogen-containing natural products which are not otherwise classified as nonprotein amino acids, amines, peptides, amines, cyanogenic glycosides, glucosinolates, cofactors, phytohormones, or primary metabolite (such as purine or pyrimidine bases). The chemical reactions and pathways resulting in the breakdown of purine alkaloids, compounds derived from purine and composed of an N-containing double ring structure. The chemical reactions and pathways resulting in the breakdown of tropane alkaloids, compounds containing the 8-methyl-8-azabicyclo(3.2.1)octane ring system. The chemical reactions and pathways resulting in the formation of substances, carried out by individual cells.
