Table 1.

Bisphenols ranked according to the mean relative peak Ca²⁺ signal induced at 10 μM, i.e., the peak Ca²⁺ signal induced by the bisphenol at 10 μM divided by the peak Ca²⁺ signal induced by progesterone at 5 μM in the same experiment.

Rank		Name	CAS number	Abbrevation	Mean relative peak Ca2+ signal at 10 μM (in %) (n = 3)	Chemical structure
Positive hits	1	Bisphenol G	127-54-8	BPG	109.02
	2	Bisphenol AF	1478-61-1	BPAF	57.95
	3	Bisphenol C	79-97-0	BPC	21.67
	4	Bisphenol A diglycidyl ether	1675-54-3	BADGE	14.79
	5	Bisphenol B	77-40-7	BPB	11.75
	6	Bisphenol BP	1844-01-5	BPBP	9.09
Negative hits	7	Bisphenol E	2081-08-5	BPE	5.37
	8	Bisphenol F	620-92-8	BPF	5.09
	9	Bisphenol S	80-09-1	BPS	4.41
	10	Bisphenol A	80-05-7	BPA	1.44

Based on their ability to induce Ca²⁺ signals, the bisphenols are categorized into “positive hits,” which induced mean relative peak Ca²⁺ signals above that of the negative controls (HTF⁺ with vehicle) ± 3 × SD (0.0 ± 3 × 2.3 = 6.9%) and “negative hits.” CAS number, abbreviation, and chemical structure are also listed in the table.
