Description

iKIX1 is an antifungal agent and resensitizes drug-resistant C. glabrata to azole antifungals in vitro. iKIX1 inhibits the interaction between the KIX domain of the mediator subunit CgGal11A and the activation domain of CgPdr1, the IC50 and Ki values are 190.2 μM and 18 μM, respectively. iKIX1 is used for the study of multidrug resistance and C. glabrata infection[1].

IC50 & Target

IC50: 190.2 μM (interaction between CgGal11A and CgPdr1)
Ki: 18 μM (interaction between CgGal11A and CgPdr1)[1]
In Vitro

iKIX1 (10-20 μg/ml) inhibits cell growth in a concentration-dependent manner in the presence of 5 µM ketoconazole (KET) in HepG2 cells[1].
FP titration curve showing the interaction of CgGal11A KIX domain with CgPdr1 AD30 fitted to a Kd of 319.7 nM. iKIX1 competes out CgPdr1 AD30 with an IC50 of 190.2 µM . In vitro binding studies, iKIX1 reveals that the Kd of the CgPdr1 activation domain (AD) for the CgGal11A KIX domain is 0.32 µM and the apparent Ki for iKIX1 is 18 µM[1].
iKIX1 (0-50 µM) inhibits Ketoconazole (KET)-induced upregulation of luciferase activity in a dose-responsive manner in a Sc pdr1Δpdr3Δ strain containing plasmid-borne CgPDR1 and 3XPDRE-luciferase[1].
A chromatin immunoprecipitation (ChIP) assay is used to examine Gal11/Med15 recruitment to Pdr1-regulated target genes in S. cerevisiae. Ketoconazole induces Gal11/Med15 rapidly recruited to the promoters of the Pdr1 target genes PDR5 and SNQ2. iKIX1 abrogates Ketoconazole-induced recruitment of Gal11/Med15 and strongly inhibits azole-induced transcription of ScPdr1 target genes[1].
iKIX1 (20 μM) has an effect on the transcription of C. glabrata Pdr1-regulated genes involved in drug efflux and MDR (CgCDR1, CgCDR2 and CgYOR1). iKIX1 alone does not significantly affect Pdr1-target gene induction. But pre-treatment with iKIX1 reduces ketoconazole-induced CgPdr1 up-regulation in a durable and concentration-dependent manner[1].
In RNA sequencing (RNA-Seq) assay of a C. glabrata SFY114 (PDR1 wild-type) strain. Azole up-regulates Pdr1-dependent genes in both yeasts, such as the drug efflux pumps ScPDR5 and CgCDR1i. KIX1 combines azole strongly blunts expression of many azole-activated and Pdr1-dependent genes in both S.cerevisiae and C. glabrata, but iKIX1 alone affects very different sets of genes in S.cerevisiae and C. glabrata. And then iKIX1 does not significantly alter the expression of PDR1 or GAL11/MED15 affects very different sets of genes in S.cerevisiae and C. glabrata[1]. iKIX1 (0-150 µM) restores the efficacy of azoles towards CgPDR1 gain-of-function mutants. It restores azole-sensitivity to PDR1 gain-of-function mutant strains in a concentration-dependent manner[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.08 mg/mL (6.86 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (6.86 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
