Latest Patents
One of Hiroyuki's noteworthy innovations is a pyridine derivative aimed at treating nocturia. The invention addresses the need for a compound suitable for pharmaceutical applications, specifically targeting the challenges presented by nocturnal voiding. Through extensive research, the inventors, including Hiroyuki, hypothesized that inhibiting placental leucine aminopeptidase (P-LAP) could maintain or increase endogenous arginine vasopressin (AVP) levels, thereby enhancing the antidiuretic effect. Their studies have shown that (2R)-3-amino-2-{[4-(substituted pyridine)-2-yl]methyl}-2-hydroxy-propanoic acid derivatives exhibit significant P-LAP inhibitory activity. The results indicated that these compounds can effectively reduce urine production by elevating endogenous AVP levels.
