As of the date of this registration statement, we have filed five patent applications with the USPTO with respect to various aspects of our HDAC small molecule delivery platform and Ropidoxuridine, our lead product candidate. The following is the status of the patent applications Shuttle has filed to date:

<div align='center'>Summary of Shuttle Pharma’s Intellectual Property Portfolio</div>

Morgan, Lewis & Bockius LLP prepared patent applications related to Ropidoxuridine (IPdR) and HDAC inhibitors, and, in the fourth quarter of 2018, found no freedom to operate (FTO) issue for Ropidoxuridine used as radiosensitizer and used with tipiracil, and HDAC inhibitors SP-1-161 and SP-2-225.

Our strategy around protection of our proprietary technology, including any innovations and improvements, is to obtain worldwide patent coverage with a focus on jurisdictions that represent significant global pharmaceutical markets. Generally, patents have a term of twenty years from the earliest priority date, assuming that all maintenance fees are paid, no portion of the patent has been terminally disclaimed and the patent has not been invalidated. In certain jurisdictions, and in certain circumstances, patent terms can be extended or shortened. We are obtaining worldwide patent protection for at least novel molecules, composition of matter, pharmaceutical formulations, methods of use, including treatment of disease, methods of manufacture and other novel uses for the inventive molecules originating from our research and development efforts. We continuously assess whether it is strategically more favorable to maintain confidentiality for the “know-how” regarding a novel invention rather than pursue patent protection. For each patent application that is filed we strategically tailor our claims in accordance with the existing patent landscape around a particular technology.

There can be no assurance that an issued patent will remain valid and enforceable in a court of law through the entire patent term. Should the validity of a patent be challenged, the legal process associated with defending the patent can be costly and time consuming. Issued patents can be subject to oppositions, interferences and other third-party challenges that can result in the revocation of the patent limit patent claims such that patent coverage lacks sufficient breadth to protect subject matter that is commercially relevant. Competitors may be able to circumvent our patents. Development and commercialization of pharmaceutical products can be subject to substantial delays and it is possible
