In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Binding of antitumor platinum compound to cells as influenced by physical factors and pharmacologically active agents, published in 1973, which mentions a compound: 15227-42-6, mainly applied to tumor cell platinum compound binding, Category: tetrahydroisoquinoline.
Tritiated cis-dichloro(dipyridine)platinum(II) (I) [15227-42-6] bound to intact Ehrlich ascites tumor cells at 37.deg. in vitro and remained associated with the acid-insoluble fraction of the cells. The extent of binding was also increased with increasing hydrogen ion [1333-74-0] concentration in the medium. The binding was enhanced markedly at 60.deg. and the maximum number of binding sites/cell was .sim.7 billion at this temperature Of 49 chems. and drugs tested, none decreased appreciably the rate and extent of binding, whereas certain heavy metals, and compounds that compromise membrane permeability enhanced the binding. Human and bovine lymphocytes had similar binding characteristics, but bound much more I/unit of cell volume.
In addition to the literature in the link below, there is a lot of literature about this compound(cis-Dichlorobis(pyridine)platinum(II))Category: tetrahydroisoquinoline, illustrating the importance and wide applicability of this compound(15227-42-6).
