Advancing PROTAC Therapeutics Through Chemistry-Guided Design of Smart Delivery Systems

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

Creating a liposomal gel with Pyrilutamide for hair loss to reduce systemic effects, similar to Xyon's gel. The discussion includes concerns about ingredient sourcing and the benefits of targeted topical treatments.

Ethosomes are suggested as an effective delivery method for topical finasteride solutions, requiring the addition of a phospholipid like soya lecithins. The user questions why do-it-yourself solutions don't commonly use ethosomes despite their potential benefits.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

The conversation discusses the delay in the PP405 Phase 2 study results, now expected by the end of 2025, and skepticism about research practices. There is also mention of optimism for Amplifica's AMP303 and a topical treatment in early testing.

Kintor plans to release pyrilutamide foam and a plant-based Koshine by year-end, with GT20029 progressing in their pipeline. Users are pleased about the absence of propylene glycol (PG) in the new products.
