    Summary
    This summary is machine-generated.

    Researchers synthesized novel 18-substituted progesterone derivatives to investigate their biological activity. However, none of the tested compounds demonstrated any significant activity in Clauberg or anti-Clauberg assays, indicating a lack of progestogenic or anti-progestogenic effects.

    Main Results:

    • Several 18-substituted progesterone derivatives were successfully synthesized.
    • The synthesized compounds were tested for biological activity.
    • No progestogenic or anti-progestogenic activity was observed in Clauberg or anti-Clauberg tests.

    Conclusions:

    • The synthesized 18-substituted progesterones lack significant biological activity in the tested assays.
    • Further structural modifications may be needed to achieve desired biological effects.
