Pone.0115460.t003 19 / 32 Open PHACTS and Drug Discovery Investigation Fig. 4. Use case C workflows 1 and 2. Open PHACTS v 1.3 API calls are shown in orange boxes along with the outcomes obtained. Bioactivity filters and other information processing operations are shown in yellow boxes with outcomes obtained in light grey boxes. Blue colored boxes show outcomes included within the manuscript. Sample input URLs are shown in S2 utilizing the `Target Pharmacology’ API. Indeed, no approved drugs are listed in DrugBank three.0 for DHCR7; nevertheless our workflow retrieves Tamoxifen and Doxorubicin as they target the anti-estrogen binding website, a protein complicated comprising DHCR7 and D8-D7 sterol isomerase. The integration of two disparate pharmacology databases supplies a much more full listing of all authorized drugs that have potent activity against any target inside the pathway, whether it is actually a single protein or a part of a complex.

CYP24A1 as a therapeutic target The pathway pharmacology information clearly show that the majority of efforts have been focused on targeting the VDR directly. Targets for novel therapeutic methods to improve VDR activation could lie upstream of ligandreceptor binding, in the degree of calcitriol catabolism by CYP24A1 or transport by Vitamin D- binding protein or DBP. CYP24A1 could be the major catabolic enzyme of calcitriol PubMed ID:http://jpet.aspetjournals.org/content/120/3/269 converting it to significantly less active calcitroic acid, so selectively inhibiting this enzyme is often expected to raise the circulating levels in the hormone.Pone.0115460.t003 19 / 32 Open PHACTS and Drug Discovery Investigation Fig. 4.
