Kitasamycin (Leucomycin) is a macrolide antibiotic. It has antimicrobial activity against a wide spectrum of pathogens.

Pirenzepine is an antimuscarinic agent which inhibits gastric acid secretion at lower doses than are required to affect gastrointestinal motility, salivary, central nervous system, cardiovascular, ocular and urinary functions.

Trimethoprim (BW 56-72, NIH 204, NSC-106568) is a bacteriostatic antibiotic mainly used in the prophylaxis and treatment of urinary tract infections.

VU 0364770 is a positive allosteric modulator(PAM) of mGlu4 with EC50 of 1.1 μM, exhibits insignificant activity at 68 other receptors, including other mGlu subtypes.

Hygromycin B (Hygrovetine), a selective antibiotic that is effective on most bacteria, fungi and higher eukaryotes, inhibits protein synthesis by interfering with translocation and causing mistranslation at the 70S ribosome.

Go 6983 (GOE 6983, Gö 6983) is a pan-PKC inhibitor against for PKCα, PKCβ, PKCγ and PKCδ with IC50 of 7 nM, 7 nM, 6 nM and 10 nM, respectively; less potent to PKCζ and inactive to PKCμ.
