Oxybenzone is a UV filter commonly used in tanning and skin protection agents. It is a derivative of benzophenone and is used as an endocrine disrupting chemical that penetrates the placental and blood-brain barriers. It impairs autophagy, alters epigenetic status and disrupts vitamin X-like receptor signaling in apoptotic neuronal cells.

ANG1005 is a brain-penetrating peptide-agent conjugate comprising a taxane derivative that features three paclitaxel molecules covalently bonded to Angiopep-2. This design facilitates crossing of the blood-brain and blood-cerebrospinal barriers, with subsequent penetration of malignant cells through the low-density lipoprotein receptor-related protein (LRP1) transport system [1] [2] [3].

SWELYYPLRANL-NH2 TFA acts as an antagonist to both E-cadherin and N-cadherin, with inhibitory effects on phage clone binding to E- or N-cad Fc chimeric proteins, exhibiting IC50 values of 0.7 μM and 0.09 μM, respectively. Additionally, it disrupts cell aggregation and is utilized to enhance drug delivery by increasing the permeability of epithelial and endothelial barriers [1].

SWELYYPLRANL-NH2 is a dual antagonist of E-cadherin and N-cadherin, effectively inhibiting the binding of phage clones to both E-cad Fc and N-cad Fc chimeric proteins with IC50 values of 0.7 μM and 0.09 μM, respectively. This compound also impedes cell aggregation and has potential applications in enhancing drug delivery by increasing epithelial and endothelial permeability barriers [1].

4-FPBUA, a semi-synthetic analog of lichen acid, enhances the functionality of cell-based blood-brain barriers (BBB) and increases the transport of β-amyloid (Aβ) in monolayer cells. Additionally, it acts as an inhibitor of mTOR, enhancing cellular autophagy (Autophagy) which can reverse BBB disruption in vivo, making it relevant for research in Alzheimer's disease.
