The letters represent the steroid numbers shown in Figure 1, Figure 2, Figure 3 and Figure 4 and Table 1, Table 2, Table 3, Table 4 and Table 5: A—(1), B—(14), C—(16), D—(18), E—(19), F—(20), G—(21), H—(23), I—(24), J—(26), K—(31), L—(40), M—(41), N—(42), O—(43), and P—(52). Steroids that belong to this group, according to the data obtained by the PASS, have confirmed more than 90% of their biological activity.
	Figure 12. The 3D graph shows the predicted and calculated wound-healing activity of selected sulfated steroids (compound numbers: 14 (95.5%), 18 (93.8%), 19 (95.2%), 21 (92.8%), 29 (96.5%), 40 (95.3%), 41 (96.3%), 42 (97.5%), 43 (98.0%), 44 (97.7%), 60 (93.3%), and 61 (94.2%).

	Figure 14. The 3D Graph (X and Y views) predicted and calculated activities of the spironolactone, which was isolated from the human urine extracts. According to PASS data, this steroid demonstrated seventeen different activities, with five activities having confidence of more than 90%. The main pharmacological properties and activities of spironolactone (73) are diuretic (99.1%), anti-hyperaldosteronism (96.3%), anti-hypertensive (94%), renal disease treatment (93.4%), and heart failure treatment (91.2%). As shown in numerous publications, spironolactone demonstrates properties as a potential diuretic, antihypertensive agent, or agent for the treatment of renal failure and heart failure, as well as an agent in the treatment of hyperaldosteronism (including Conn’s syndrome) and female hirsutism (due to additional antiandrogenic actions). All these properties and activities are confirmed by the PASS data as shown in this figure and shown in Table 5.
