The process of discovery for highly potent prostaglandin D(2) (PGD(2)) receptor antagonists is reported. A series of N-(p-alkoxy)benzoyl-2-methylindole-4-acetic acids were synthesized and identified as a new class of selective PGD(2) receptor antagonists. Most of them exhibited strong PGD(2) receptor antagonism in binding studies and the cAMP formation assay. The structure-activity relationships (SAR), including subtype selectivity of the synthesized compounds, are also discussed.
Tamoxifen (TAM) is commonly used as an adjuvant treatment for breast cancer. Although patients taking TAM are often taking medications for comorbidities, data regarding the interaction of TAM with other medications are limited. Thus, this study was carried out to determine whether medications co-prescribed with TAM significantly influence the plasma concentrations of TAM and its metabolites (N-desmethyltamoxifen; N-DMT and 4-hydroxytamoxifen; 4-OHT) in 98 women diagnosed with breast cancer. Participants taking diuretics had significantly higher plasma concentrations of TAM and N-DMT than participants not taking a diuretic. Arthritis/pain medication intake was negatively associated with plasma TAM concentrations. Chemotherapeutic agents, allergy drugs, anti-depressants, and diabetes medications did not significantly alter plasma TAM or metabolite concentrations. This suggests that diuretic or an arthritis/pain medication may affect TAM metabolism.
A series of 2-substituted N-benzyl benzimidazole containing molecules has been synthesized and its structure-activity relationship for the human DP receptor has been evaluated. Selective DP antagonists with nanomolar potency for the DP receptor were identified in this novel series of benzimidazoles.
