Goodwill and Intangible Assets Disclosure [Text Block]	3. Intangible Assets In conjunction with its acquisition of Moleculin, LLC in 2016, the Company recognized an intangible asset for acquired in-process research and development (IPR&D) related to the acquired WP1066 portfolio. As the Company's WP1066 portfolio is currently in development, the Company’s IPR&D intangible asset will not be amortized until development is complete. If the associated research and development effort is abandoned, the Company’s IPR&D intangible asset will be written-off and the Company will record a noncash impairment loss on its statements of operations. For those compounds that reach commercialization, the IPR&D assets will be amortized over their estimated useful lives. IPR&D was $11.1 million as of December 31, 2024 and 2023, respectively.
