(A). Number of indexed publications in a PubMed literature search for different members of the cytochalasans. (B). Number of indexed publications in a PubMed literature search for CB (1) vs. CD (2) between January 1967 and June 2023. (C). Number of indexed publications in a PubMed literature search for CA (1), CC (23), CE (55), CF (48), and CH (57) between January 1967 and June 2023. To search for indexed publications for different cytochalasan subclasses, the keywords “alachalasin”, “aspochalasin”, “chaetoglobosin”, “pyrichalasin”, and “trichalasin” were used. For the remainder, “cytochalasin A” was used for CA (1), “cytochalasin B” for CB (2), “cytochalasin C” for CC (23), “cytochalasin F” for CF (48), and “cytochalasin H” for CH (57), spanning a time interval from 1967 until June 2023. Note the overwhelming share of publications indexing either CB (1) or CD (2).
