Need help building a regular expression for Nginx?

Question

Nginx

Hello. Need help writing a regular expression. Since only the elite can learn this elven magic, I turn to you for help.
Condition:
There is a url:

http://example.com/assets/Irbis/moto/IRBIS%20XR250/DPP_0015-400x400.png

however, there is nothing along that path.
There is a way:

$document_root/image/data/Irbis/moto/IRBIS%20XR250/DPP_0015.png

here lies the image.
Task:
Need to address

http://example.com/assets/Irbis/moto/IRBIS%20XR250/DPP_0015-400x400.png

there was an internal redirect to

$document_root/image/data/Irbis/moto/IRBIS%20XR250/DPP_0015.png

.
Note:
Url can be like:

http://example.com/assets/(.*)/(.*)/(.*)/(.*)-400x400.png

(the number of folders in the path after assets can be anything, the file extension is (png|jpg) ).
Please issue the answer as a condition for the Nginx config.
