In the Licensing Arrangements section (Note 5), Salarius obtained an exclusive license right for an LSD1 inhibitor from the University of Utah Research Foundation and an exclusive right for a DNMT1 inhibitor from NUPOTENTIAL. The LDS1 molecule was patented on August 15, 2011. The DNMT1 inhibitor was patented during October 2009. The recorded value of both Inhibitor licenses was based upon the value of the equity exchanged to procure it. Intangible assets with finite lives are capitalized and are amortized over their estimated useful lives, which was determined to be 20 years for the LSD1 Inhibitor and the DNMT1 Inhibitor. As of December 31, 2018, and December 31, 2017 the remaining amortization period for finite-lived intangible assets ranging from 13-20 years and 14 years, respectively. Amortization expense related to finite-lived intangible assets was as follows:
|  | December 31, 2018 |  |  | December 31, 2017 |
Amortization Expense—Intangibles |  | $ | 4,442 |  |  | $ | 4,340 |
The estimated amortization expense for each of the next five years associated with Salarius’ finite-lived intangible assets as of December 31, 2018 is $9,965. Amortization expense is included in general and administrative expense.
