Parbendazole
Based on 8 publication(s) in Google Scholar
Parbendazole (SKF‑29044) is an orally active benzimidazole carbamate compound with multiple biological activities. Parbendazole binds to free tubulin and inhibits microtubule polymerization; it also activates the JNK/c‑Jun signaling axis and upregulates the expression of the downstream axonal repulsion factor Sema3A. Parbendazole upregulates KAL-1 mRNA expression, reduces nerve growth factor levels, and promotes the terminal differentiation of normal human epidermal keratinocytes. Parbendazole induces apoptosis in differentiated acute myeloid leukemia monocytes and exerts antileukemic activity in a mouse xenograft model of acute myeloid leukemia. Parbendazole exhibits broad-spectrum anthelmintic activity against various animal nematodes. Parbendazole is used in research related to acute myeloid leukemia and parasitic infections.

In Vitro
Parbendazole (PBZ) exhibits extremely potent anti-survival activity against THP-1 acute myeloid leukemia cells, with an IC50 of 0.6 nM at 48 h and an IC50 of 0.3 nM at 72 h. At concentrations ≥50 nM, it effectively induces rapid monocytic differentiation of THP-1 acute myeloid leukemia cells, followed by apoptosis, which is accompanied by upregulation of the KLF4/DPYSL2A differentiation axis[1].
Parbendazole (100 nM; 48 h) exerts broad and potent differentiation-inducing and pro-apoptotic effects on acute myeloid leukemia cell lines with different subtypes and genetic backgrounds, while exhibiting limited toxicity to normal human hematopoietic progenitor cells; it effectively induces monocytic differentiation, triggers apoptosis, and upregulates the KLF4/DPYSL2A axis in primary human AML-PDX cells[1].
Parbendazole (0.01-1 μM; 48 h) induces the expression of the Sema3A gene and protein in normal human epidermal keratinocytes in a dose-dependent manner[2].
Parbendazole (1 μM; 48 h) downregulates NGF mRNA expression and upregulates KAL‑1 mRNA expression in normal human epidermal keratinocytes (NHEKs)[2].
Parbendazole (1 μM; 24 h) promotes the phosphorylation of JNK and c‑Jun in normal human epidermal keratinocytes (NHEKs)[2].
Parbendazole (1-10 μM; 24 h) increases the mRNA and protein expression levels of Sema3A in an in vitro reconstructed human epidermis (RHE) model[2].
Parbendazole hydrochloride: Wild-type Physarum polycephalum CLd-AXE tubulin completely inhibits in vitro microtubule assembly at 2-5 μM parbendazole, whereas mutant BEN210-AXE tubulin retains full microtubule assembly capacity even at parbendazole concentrations as high as 50 μM[3].
Parbendazole inhibits the growth of wild-type Physarum polycephalum CLd‑AXE myxamoebae and the in vitro assembly of their tubulin.
Parbendazole exhibits significant pH-dependent ultraviolet absorption characteristics, and shows a pronounced red shift in alkaline methanol medium compared to neutral and acidic methanol conditions[4].

In Vivo
Parbendazole (5 mg/kg; i.v.; single injection) exhibits rapid distribution, a long elimination half-life of 720.0 min, and very low total excretion via urine and feces over 5 days in healthy goats[4].
Parbendazole (100 mg/kg; p.o.; daily; 28 consecutive days) exerts significant in vivo anti-leukemic activity in the AML PDX model by reducing leukemia burden, inducing leukemic cell monocytic differentiation, and prolonging animal survival[1].
