Cyclotriazadisulfonamide (CADA) is a specific CD4-targeted HIV entry inhibitors. Cyclotriazadisulfonamide (CADA) inhibits the co-translational translocation of human CD4 (huCD4) into the ER lumen in a signal peptide (SP)-dependent way[1][2].
Cyclotriazadisulfonamide (CADA) significantly decreases the amount of cell surface CD4 -the main receptor for HIV -without altering the expression of any other cellular receptor examined so far[1].Cyclotriazadisulfonamide (CADA) exhibits an EC50 of 0.4 μg/mL for CD4 in MO-DC cells. Treatment of MO-DC with 10 μg/mL of CADA results in 83% downregulation of cell surface CD4, an effect that is similar to that observed for CADA treatment of CD4+ T cells[1].CADA prevents MT-4 cells from HIV-1 and SIV infection (EC50 are 0.7 and 1.2 g/ml, respectively)[1].

Small Molecule Cyclotriazadisulfonamide Abrogates the Upregulation of the Human Receptors CD4 and 4-1BB and Suppresses In Vitro Activation and Proliferation of T Lymphocytes
Front Immunol 2021 Apr 21;12:650731.PMID:33968048DOI:10.3389/fimmu.2021.650731.
The small molecule Cyclotriazadisulfonamide (CADA) down-modulates the human CD4 receptor, an important factor in T cell activation. Here, we addressed the immunosuppressive potential of CADA using different activation models. CADA inhibited lymphocyte proliferation with low cellular toxicity in a mixed lymphocyte reaction, and when human PBMCs were stimulated with CD3/CD28 beads, phytohemagglutinin or anti-CD3 antibodies. The immunosuppressive effect of CADA involved both CD4+ and CD8+ T cells but was, surprisingly, most prominent in the CD8+ T cell subpopulation where it inhibited cell-mediated lympholysis. Immunosuppression by CADA was characterized by suppressed secretion of various cytokines, and reduced CD25, phosphoSTAT5 and CTPS-1 levels. We discovered a direct down-modulatory effect of CADA on 4-1BB (CD137) expression, a survival factor for activated CD8+ T cells. More specifically, CADA blocked 4‑1BB protein biosynthesis by inhibition of its co-translational translocation into the ER in a signal peptide-dependent way. Taken together, this study demonstrates that CADA, as potent down-modulator of human CD4 and 4‑1BB receptor, has promising immunomodulatory characteristics. This would open up new avenues toward chemotherapeutics that act as selective protein down-modulators to treat various human immunological disorders.
Unsymmetrical Cyclotriazadisulfonamide (CADA) compounds as human CD4 receptor down-modulating agents
J Med Chem 2011 Aug 25;54(16):5712-21.PMID:21800875DOI:10.1021/jm2002603.
Cyclotriazadisulfonamide (CADA) inhibits HIV at submicromolar levels by specifically down-modulating cell-surface and intracellular CD4. The specific biomolecular target of CADA compounds is unknown, but previous studies led to an unsymmetrical binding model. To test this model, methods were developed for effective synthesis of diverse, unsymmetrical CADA compounds. A total of 13 new, unsymmetrical target compounds were synthesized, as well as one symmetrical analogue. The new compounds display a wide range of potency for CD4 down-modulation in CHO·CD4-YFP cells. VGD020 (IC(50) = 46 nM) is the most potent CADA compound discovered to date, and VGD029 (IC(50) = 730 nM) is the most potent fluorescent analogue. Structure-activity relationships are analyzed from the standpoint of additive or nonadditive energy effects of different substituents. They appear to be consistent with the zipper-type mechanism in which entropy costs are reduced for additional stabilizing interactions between the small molecule and its protein target.
Reduction of Progranulin-Induced Breast Cancer Stem Cell Propagation by Sortilin-Targeting Cyclotriazadisulfonamide (CADA) Compounds
J Med Chem 2021 Sep 9;64(17):12865-12876.PMID:34428050DOI:10.1021/acs.jmedchem.1c00943.
Cyclotriazadisulfonamide (CADA) compounds selectively down-modulate two human proteins of potential therapeutic interest, cluster of differentiation 4 (CD4) and sortilin. Progranulin is secreted from some breast cancer cells, causing dedifferentiation of receiving cancer cells and cancer stem cell proliferation. Inhibition of progranulin binding to sortilin, its main receptor, can block progranulin-induced metastatic breast cancer using a triple-negative in vivo xenograft model. In the current study, seven CADA compounds (CADA, VGD020, VGD071, TL020, TL023, LAL014, and DJ010) were examined for reduction of cellular sortilin expression and progranulin-induced breast cancer stem cell propagation. In addition, inhibition of progranulin-induced mammosphere formation was examined and found to be most significant for TL020, TL023, VGD071, and LAL014. Full experimental details are given for the synthesis and characterization of the four new compounds (TL020, TL023, VGD071, and DJ010). Comparison of solubilities, potencies, and cytotoxicities identified VGD071 as a promising candidate for future studies using mouse breast cancer models.
Preprotein signature for full susceptibility to the co-translational translocation inhibitor Cyclotriazadisulfonamide
Traffic 2020 Feb;21(2):250-264.PMID:31675144DOI:10.1111/tra.12713.
Cyclotriazadisulfonamide (CADA) inhibits the co-translational translocation of human CD4 (huCD4) into the endoplasmic reticulum lumen in a signal peptide (SP)-dependent way. We propose that CADA binds the nascent huCD4 SP in a folded conformation within the translocon resembling a normally transitory state during translocation. Here, we used alanine scanning on the huCD4 SP to identify the signature for full susceptibility to CADA. In accordance with our previous work, we demonstrate that residues in the vicinity of the hydrophobic h-region are critical for sensitivity to CADA. In particular, exchanging Gln-15, Val-17 or Pro-20 in the huCD4 SP for Ala resulted in a resistant phenotype. Together with positively charged residues at the N-terminal portion of the mature protein, these residues mediate full susceptibility to the co-translational translocation inhibitory activity of CADA towards huCD4. In addition, sensitivity to CADA is inversely related to hydrophobicity in the huCD4 SP. In vitro translocation experiments confirmed that the general hydrophobicity of the h-domain and positive charges in the mature protein are key elements that affect both the translocation efficiency of huCD4 and the sensitivity towards CADA. Besides these two general SP parameters that determine the functionality of the signal sequence, unique amino acid pairs (L14/Q15 and L19/P20) in the SP hydrophobic core add specificity to the sensitivity signature for a co-translational translocation inhibitor.
Reduced DNAJC3 Expression Affects Protein Translocation across the ER Membrane and Attenuates the Down-Modulating Effect of the Translocation Inhibitor Cyclotriazadisulfonamide
Int J Mol Sci 2022 Jan 6;23(2):584.PMID:35054769DOI:10.3390/ijms23020584.
One of the reported substrates for the endoplasmic reticulum (ER) translocation inhibitor Cyclotriazadisulfonamide (CADA) is DNAJC3, a chaperone of the unfolded protein response during ER stress. In this study, we investigated the impact of altered DNAJC3 protein levels on the inhibitory activity of CADA. By comparing WT DNAJC3 with a CADA-resistant DNAJC3 mutant, we observed the enhanced sensitivity of human CD4, PTK7 and ERLEC1 for CADA when DNAJC3 was expressed at high levels. Combined treatment of CADA with a proteasome inhibitor resulted in synergistic inhibition of protein translocation and in the rescue of a small preprotein fraction, which presumably corresponds to the CADA affected protein fraction that is stalled at the Sec61 translocon. We demonstrate that DNAJC3 enhances the protein translation of a reporter protein that is expressed downstream of the CADA-stalled substrate, suggesting that DNAJC3 promotes the clearance of the clogged translocon. We propose a model in which a reduced DNAJC3 level by CADA slows down the clearance of CADA-stalled substrates. This results in higher residual translocation into the ER lumen due to the longer dwelling time of the temporarily stalled substrates in the translocon. Thus, by directly reducing DNAJC3 protein levels, CADA attenuates its net down-modulating effect on its substrates.
