VNRX-14079
VNRX-14079 is an antibacterial agent and PBP2 inhibitor, with an IC50 value of 1.7 μM against wild-type Neisseria gonorrhoeae PBP2. VNRX-14079 forms a covalent bond with Ser310 of PBP2, interacts with multiple residues of PBP2 to stabilize the complex, and induces an inward conformational change of the β3-β4 loop in chimeric PBP2. VNRX-14079 exhibits antibacterial activity against Ceftriaxone (HY-B0712)-resistant Neisseria gonorrhoeae strains. VNRX-14079 can be used in the research of gonorrhea.

Biological Activity
VNRX-14079 binds to PBP2 of wild-type *Neisseria gonorrhoeae* (strain FA19) with an IC50 of 1.7 µM[1].
VNRX-14079 binds to chimeric Neisseria gonorrhoeae PBP2 from strain H041, with an IC50 of 3.0 µM[1].
VNRX-14079 (24 h) exhibits potent antibacterial activity against most Neisseria gonorrhoeae strains producing non-mosaic and mosaic PBP2[1].
VNRX-14079 (4× MIC-16× MIC; 2-24 h) exhibits rapid bactericidal activity against *Neisseria gonorrhoeae* ATCC 49226, WHO Q and H041. At 4× and 16× MIC, it reduces bacterial counts by ≥2 log10 within 6 hours and lowers them to undetectable levels within 24 hours[1].

Animal Model:NCI BALB/c (female, 6-7 weeks old, pretreated with 17β oestradiol and antibiotics to suppress commensal microbiota, vaginally infected with ceftriaxone-resistant Neisseria gonorrhoeae H041)[1]
-
Dosage:10 mg/kg; 200 mg/kg; 150 mg/kg
-
Administration:s.c.; q12h (total 2 doses on day 1); q24h (single dose on day 1); q8h (total 3 doses on day 1)
-
Result:Achieved 80% bacterial clearance by day 4 with statistically significant reduction in culture-positive mice relative to vehicle controls (P < 0.01) at 10 mg/kg q12h.
Achieved 100% clearance by day 3 with predicted 44% free unbound drug concentration above the MIC over 24 hours at 200 mg/kg q24h.
Resulted in 90% clearance by day 2 at 150 mg/kg q12h.
Achieved 100% clearance by day 2 at 150 mg/kg q8h.
Showed reduced average bacterial burden consistent with clearance rates across all doses.
Detected no evolution of spontaneous gonococcal mutants or adverse effects across all doses.
