    Representative absorbance spectra of AMB-PEG 2 and unconjugated AMB formulations prepared in buffers with varying hydrophobicity. 20 mM AMB-PEG 2 and unconjugated AMB formulations were prepared in DMSO and resuspended in 20% and 48% ACN buffers containing 4.3% acetic acid, as well as <t>PBS-EDTA,</t> to a final concentration of 2 mM AMB. As buffer hydrophobicity increases with higher ACN concentrations, the A 348 /A 409 ratio decreases, implying that AMB-PEG is increasingly in its monomeric form. As AMB-PEG 1 and 2 have similar UV-visible absorption profiles, with identical peak height ratios in all buffers tested, data for AMB-PEG 1 is not shown. AMB-PEG formulations that have been subjected to buffer exchange to PBS-EDTA through a 10 kDa centrifugal filter have the same UV-visible absorption spectra as the initial formulation of AMB-PEG in PBS-EDTA, which contains 10% DMSO.

    Millipore calpain reaction buffer
    Schematic diagram showing the relationship of <t>calpain/NF-κB/inflammation/NVU</t> damage after CCI in mice. Traumatic brain injury induces calcium overload, which, in turn, upregulates calpain. Calpain may downregulate IκB and activate NF-κB. NF-κB induces activation of TNF-α, iNOS, ICAM-1, and MMP-9. These inflammatory substances induce degradation of basal lamina and tight junction proteins, resulting in NVU disruption, leading to brain edema. MDL28170 could reverse those changes. NF-κB: Nuclear factor-κB; NVU: Neurovascular unit; CCI: Controlled cortical impact; IκB: Inhibitory-κB; TNF-α: Tumor necrosis factor-α; iNOS: Inducible nitric oxide synthase; ICAM-1: Intracellular adhesion molecule-1; MMP-9: Matrix metalloproteinase-9.

    (A) Reverse phase chromatogram of AMB-PEG and unconjugated AMB, with eluted peaks detected at 406 nm. 50 μL of AMB-PEG 1 and 2, and 10 μL of unconjugated AMB dispersed in PBS-EDTA and 48% ACN respectively were injected into a C18 reverse phase column and eluted isocratically in a 48% ACN buffer at a flow rate of 0.5 ml/min for 40 minutes. Peaks were detected at 406 nm. The AMB-PEG conjugate has a shorter retention time, implying that it is more hydrophilic. From the AMB-PEG samples, AMB-PEG conjugate and free AMB (based on the retention time of unconjugated AMB) fractions were collected for further analysis via size exclusion chromatography. (B) Size exclusion chromatogram of AMB-PEG 2 and unconjugated AMB, as well as the relevant fractions collected from RPC, in a 20% ACN mobile phase. 20 mM of AMB-PEG 2 formulations and unconjugated AMB in DMSO were prepared and resuspended at 2 mM in a 20% ACN buffer. 50 μL of these samples (unconjugated AMB diluted tenfold prior to analysis) and the peak fractions collected previously from RPC were passed through a size exclusion column and eluted peaks were detected at 406 nm. Unconjugated AMB was eluted later compared to the AMB-PEG conjugate, implying that it has a smaller hydrodynamic volume compared to AMB-PEG in 20% ACN. The previously collected AMB-PEG conjugate and free AMB peak fractions had similar retention times as the AMB-PEG 2 formulation and unconjugated AMB samples respectively, thus verifying their respective peak identities. AMB-PEG 1 and 2 have identical elution profiles. (C) Size exclusion chromatogram of AMB-PEG and unconjugated AMB dispersed in PBS-EDTA. 3 μL of 2 mM AMB-PEG formulations that have been retained by 10 kDa centrifugal filters (Millipore) and 50 μL of the supernatant obtained from unconjugated AMB were analysed using a Superdex 75 size exclusion column and eluted peaks detected at 406 nm. In a PBS-EDTA mobile phase, unconjugated AMB has a shorter retention time of 20 minutes compared to AMB-PEG at 40 minutes, implying that AMB-PEG has a smaller hydrodynamic volume under these experimental conditions.

    (A) AMB-PEG reaction scheme. The NHS ester on MS(PEG) 4 reacts with the primary amine (–NH2) group on AMB at a 1:1 molar ratio, generating conjugated AMB-PEG via amide bond formation. (B) Solubility of AMB-PEG at varying AMB:PEG molar ratios. AMB-PEG mixtures and unreacted AMB were prepared in DMSO, incubated for 2 hours and then (i) dispersed to a final concentration of 2 mM in PBS-EDTA, containing 10% DMSO by volume. (ii) The mixtures were then centrifuged to facilitate the observation of insoluble precipitates. Higher molar ratios yielded a suspension of yellow particles that precipitated upon centrifugation, similar to what was observed with unconjugated AMB.

    Aqueous solubility of AMB-PEG 1 and 2. Increasing amounts of AMB-PEG formulations were added to PBS-EDTA, and post-centrifugation, the concentration of soluble AMB-PEG in the supernatants quantified based on their absorbance at 365 nm. Error bars denote the standard deviation between 3 independent formulations. Dotted line represents the theoretical condition where AMB formulation is completely soluble (i.e. concentration of total AMB = concentration of soluble AMB).
