== Function ==
[https://www.uniprot.org/uniprot/ARGI2_HUMAN ARGI2_HUMAN] May play a role in the regulation of extra-urea cycle arginine metabolism and also in down-regulation of nitric oxide synthesis. Extrahepatic arginase functions to regulate L-arginine bioavailability to NO synthase. Since NO synthase is found in the penile corpus cavernosum smooth muscle, the clitoral corpus cavernosum and the vagina, arginase II plays a role in both male and female sexual arousal. It is therefore a potential target for the treatment of male and female sexual arousal disorders.

== Publication Abstract from PubMed ==
Recent efforts to identify new highly potent arginase inhibitors have resulted in the discovery of a novel family of (3R,4S)-3-amino-4-(3-boronopropyl)pyrrolidine-3-carboxylic acid analogues with up to a 1000-fold increase in potency relative to the current standards, 2-amino-6-boronohexanoic acid (ABH) and N-hydroxy-nor-l-arginine (nor-NOHA). The lead candidate, with an N-2-amino-3-phenylpropyl substituent (NED-3238), example 43, inhibits arginase I and II with IC50 values of 1.3 and 8.1 nM, respectively. Herein, we report the design, synthesis, and structure-activity relationships for this novel series of inhibitors, along with X-ray crystallographic data for selected examples bound to human arginase II.
