It has been decided that publication of ''HETEROCYCLES'' will be suspended as of December 2023 due to various circumstances. … ''HETEROCYCLES'' has completed its role of promoting the recognition of heterocyclic chemistry as a discipline that traverses various fields rather than being limited to one domain.

The journal's articles are preserved on CLOCKSS and were released ("triggered") in June 2024. The Japan Institute of Heterocyclic Chemistry has not granted public access. In July 2024, ''Chemistry World'' reported that the institute had initiated legal action against CLOCKSS related to the release of the archive.
