CycloSyn Therapeutics — Organelle-Targeted Drug Delivery
RUO & Pre-Clinical · V4 Platform Ready

Drug delivery, solved
at the organelle level.

CycloSyn Therapeutics: Transforming the Future of Precision Drug Delivery

The Problem

Current drug delivery fails at the subcellular level.

80% of drug candidates fail not because they don't work — but because they can't reach the right place inside the cell.

🎯
No Organelle Specificity
LNPs and traditional nanoparticles deliver to the cell membrane — not the mitochondria, nucleus, or lysosomes where disease actually originates.
⚡
Low Bioavailability
Active payloads degrade before reaching disease sites, drastically reducing therapeutic effect at the intended cellular target.
🔒
Single-Purpose Platforms
Existing delivery systems are designed for one indication. Repurposing requires a full rebuild — costing years and hundreds of millions.

CycloSyn Cascade Architecture™ V4

A modular, four-layer platform engineered for precision.

Each layer is independently programmable. Swap the targeting element and the entire system redirects — without rebuilding the platform.

LAYER 01 +
β-CDP Core
Epichlorohydrin-cross-linked β-cyclodextrin polymer matrix. High-capacity payload encapsulation. Patent-protected composition and architecture.
Particle size: 60–80 nm · PDI <0.18 · Yield ≥70% · Drug loading efficiency >85% · Biocompatible polymer backbone with no known immunogenicity at therapeutic concentrations.
LAYER 02 +
PBAE Stealth/XR Shell
pH-responsive poly(β-amino ester) interface. Activates at acidic pH ~6.0 inside target organelles — silent in healthy tissue at pH 7.4.
Zeta potential shifts from neutral at pH 7.4 → +20–30mV at pH 6.0, confirming PBAE switching. Release ratio ≥5× at disease pH vs. physiological pH. Patent Claim 34.
LAYER 03 +
Targeting Layer
Programmable targeting element — high-MW hyaluronic acid (500–700 kDa) for CD44-mediated uptake, or a formulation-specific targeting peptide (e.g., folate receptor) depending on indication. Swappable without a platform rebuild.
Post-coating size: 100–150 nm · Zeta -10 to -20mV confirming successful HA deposition · CD44 overexpressed 3–10× on cancer cells, inflamed tissue, and macrophages — giving the platform inherent tissue selectivity.
LAYER 04 +
PC:SM Lipid Shell
DPPC:Sphingomyelin 70:30 molar ratio. Provides biocompatible stealth, membrane interplay, and fusion-ready framing for cellular entry.
70:30 PC:SM molar ratio is patent-critical specification (Patent Claim 4). Sphingomyelin content modulates membrane fluidity for optimal endosomal escape. Provides immune evasion in circulation — extending plasma half-life.
1
BloodstreamPC:SM shell provides stealth
Lipid outer coat mimics cell membranes, evading immune recognition during systemic circulation.
2
HA TargetingBinds CD44 receptors
Hyaluronic acid layer locks onto CD44 receptors, which are 3–10× overexpressed on diseased cells.
3
Cell UptakeReceptor-mediated endocytosis
CD44 binding triggers active uptake into the cell via receptor-mediated endocytosis — not passive diffusion.
4
AcidificationpH drops to ~6.0
As the endosome matures, its internal pH drops from 7.4 to ~6.0 — activating the PBAE shell.
5
PBAE ActivatesShell opens, payload freed
At pH ~6.0, the PBAE coating protonates, destabilizes, and releases the therapeutic payload with precision.
6
Organelle DeliveryPrecise intracellular targeting
Cell-penetrating peptides and organelle-targeting sequences direct the freed payload to mitochondria, nucleus, or lysosome.

Plaque Regression
2025 published study · ApoE⁻/⁻ murine model
Published 2025Using the exact CycloSyn β-CDP + Ferulic Acid architecture, a peer-reviewed study showed 57% atherosclerotic plaque regression in the gold-standard ApoE knockout mouse model.

Cellular Uptake Ratio
pH-selective · Gate 4 validated
Smart selectivityThe platform takes up 5× more payload at acidic pH 6.5 (disease environment) than neutral pH 7.4 (healthy tissue) — confirming the platform is selectively active only where it's needed.

Functional efficacy data available upon Gate 5 completion.
