HMN-154 interacts with NF-YB and thereby interrupts the binding of the NF-Y heterotrimer to DNA. NF-YB and thymosin β-10 are specific cellular binding proteins of HMN-154 and that this shared region is necessary for the binding to HMN-154. HMN-154 inhibits DNA binding of NF-Y to the human major histocompatibility complex class II human leukocyte antigen DRA Y-box sequence in a dose-dependent manner. HMN-154 shows very strong cytotoxicity against KB and colon38 cells with an IC50 value of 0.0026 and 0.003 μg/mL, respectively. HMN-154/BSA binds recombinant NF-YB or thymosin β-10 and the binding is inhibited by the addition of HMN-154 as the competitor. The binding between HMN-154 and NF-YB is specific and depends on its cytotoxicity[1].

HMN-214, an orally bioavailable prodrug of HMN-176, is an inhibitor of polo-like kinase-1 (plk1), with antitumor activity.
IC50 & Target[2]
PLK1
体外研究 (In Vitro)
HMN-214 is a prodrug of HMN-176. HMN-176 shows potent activities against 22 human tumor cell lines, with a mean IC50s of 118 nM[1]. HMN-176 (3-300 nM) inhibits luciferase expression driven by the MDR1 promoter in a dose dependent manner in HeLa cells. HMN-176 (30-3000 nM) also dose-dependently suppresses complex formation on the Y-box[3]. HMN-214 (3.3 μM) enhances luciferase expression relative to vehicle control with the 1,4C-1,4Bis polymer (11-fold) and PEI (37-fold) in PC3-PSMA cells. HMN-214 (≥ 3.3 μM) significantly reduces cell proliferation, causes considerable changes in cell morphology in MB49 cells[4].

HMN-214 (33 mg/kg, p.o.) converts to HMN-176 in rats. HMN-214 has no effect on the conduction velocity and the amplitude of action potentials in the aciatic and tibial nerves. HMN-214 (20 mg/kg, p.o.) exhibits antitumor activity in mice[1]. HMN-214 (10, 20 mg/kg, p.o.) decreases MDR1 mRNA expression in nude mice bearing KB- and KB-A.1.-derived tumors[3].

Cell Assay [4]
Cell proliferation in case of different treatment conditions, relative to untreated control cells (treated as 100% viable, or a live control), is quantified using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), a yellow colored reagent which is converted to formazan (a purple dye) by living cells. For screening experiments, transfections are carried out in 96-well cell culture plates, that are seeded with 50,000 cells per well. Following 48 h of transfection, 10 μL of MTT reagent is added to the cells and incubated at 37°C for 2-4 h, and the cells are then lysed by adding 20 μL of MTT detergent and incubated for an additional 2 h at room temperature. Inhibitor dose-optimization transfections are carried out in 24-well plates that are seeded with 50,000 cells per well. After 48 h, 20 μL MTT reagent is added, followed by 100 μL of MTT detergent for lysis for 2 h[4].

Animal Administration [3]
The ground HMN-214 is suspended with an agate pestle by gradually adding 0.5% methylcellulose 4000 solution to make a 3 mg/mL suspension. This is additionally diluted with methylcellulose 4000 solution to obtain suspensions of the appropriate concentration. Tumor tissue is grown in advance by s.c. transplantation into nude mice. The resulting tumors are removed, cut into cubic fragments of 8 mm3, and transplanted s.c. into the right axillary region of nude mice with a trocar. When the theoretical volume of the tumor had reached about 145 mm3, oral administration of HMN-214 is started (day 1)[3].

HMN-176 is a stilbene derivative which inhibits mitosis, interfering with polo-like kinase-1 (plk1), without significant effect on tubulin polymerization.
IC50 & Target
PLK1[5]
体外研究 (In Vitro)
HMN-176 (2.5 μM) greatly increases the duration of mitosis in hTERT-RPE1 and CFPAC-1 Cell lines. The effect of HMN-176 on spindle morphology does not appear to be related to effects on microtubule polymerization. HMN-176 (2.5, 0.25, and 0.025 μM) inhibits aster formation in a concentration dependent manner[1]. HMN-176 (0.1, 1.0, or 10.0 µg/mL) demonstrates inhibitory effects in multiple tumors, with notable activity seen in breast, nonsmall-cell lung, and ovarian cancer specimens. HMN-176 demonstrates activity towards 63% of the breast (5/8), 67% of the non-small cell lung (4/6), and 57% of the ovarian (4/7) tumor specimens treated with 10.0 µg/mL[2]. HMN-176 shows potent cytotoxicity, with a mean IC50 value of 118 nM. HMN-176 displays similar cytotoxicity against tumors with various characteristics from different organs[3]. Treatment with 3 μM HMN-176 suppresses the expression of MDR1 mRNA by 56%. HMN-176 has no significant effect on the residual promoter activity[4].

Cell Assay [3]
Cells to be tested are seeded into a 96-well microplate at a density of 3 ×103-1×104 cells/well. Drugs are added the next day and the plate is incubated for 72 h at 37 °C in a humidified incubator (5% CO2, 95% air). The inhibition of growth is measuredby the MTT assay, and the concentration required to produce 50% inhibition of growth (IC50) calculated by the Scansoft 96 software program. The IC50 values for HMN-176 andreference agents are presented. Briefly, for each compound the mean IC50 value for all cell lines tested is calculated and the difference between the individual IC50 values and the mean IC50 value (log10) displayed by a bar projecting to the right or left of the mean. The resistance index is calculated as (IC50 value for drug-resistant cell line)/(IC50 for parent cell line).

Animal Administration [3]
14C-HMN-214 and 14C-HMN176 are p.o. to male SD rats at doses of 33 (equivalent to 30 mg/kg of HMN-176) and 30 mg/kg, respectively. Blood samples are collected at designated times and plasma levels of radioactivity determined with a liquid-scintillation counter. In addition, unlabeled HMN-214 (33 mg/kg) is administered to male rats and plasma concentrations of HMN-214 and HMN-176 are determined by high performance liquid chromatography.
