- Synthesis of Novel Tetrahydroisoquinoline CXCR4 Antagonists with Rigidified Side-Chains
-
A structure-activity relationship study of potent TIQ15-derived CXCR4 antagonists is reported. In this investigation, the TIQ15 side-chain was constrained to improve its drug properties. The cyclohexylamino congener 15a was found to be a potent CXCR4 inhi

- A structure-activity analysis of biased agonism at the dopamine D2 receptor
-
Biased agonism offers an opportunity for the medicinal chemist to discover pathway-selective ligands for GPCRs. A number of studies have suggested that biased agonism at the dopamine D2 receptor (D2R) may be advantageous for the treatment of neuropsychiatric disorders, including schizophrenia. As such, it is of great importance to gain insight into the SAR of biased agonism at this receptor. We have generated SAR based on a novel D2R partial agonist, tert-butyl (trans-4-(2-(3,4-dihydroisoquinolin- 2(1H)-yl)ethyl)cyclohexyl)carbamate (4). This ligand shares structural similarity to cariprazine (2), a drug awaiting FDA approval for the treatment of schizophrenia, yet displays a distinct bias toward two different signaling end points. We synthesized a number of derivatives of 4 with subtle structural modifications, including incorporation of cariprazine fragments. By combining pharmacological profiling with analytical methodology to identify and to quantify bias, we have demonstrated that efficacy and biased agonism can be finely tuned by minor structural modifications to the head group containing the tertiary amine, a tail group that extends away from this moiety, and the orientation and length of a spacer region between these two moieties.

- Development of Irreversible Diphenyl Phosphonate Inhibitors for Urokinase Plasminogen Activator
-
In this letter we report the synthesis and biochemical evaluation of selective, irreversible diphenyl phosphonate inhibitors for urokinase plasminogen activator (uPA). A diphenyl phosphonate group was introduced on the substratelike peptide Z-D-Ser-Ala-Arg, and modification of the guanidine side chain was investigated. A guanylated benzyl group appeared the most promising side chain modification. A kapp value in the 103 M -1 s-1 range for uPA was obtained, together with a selectivity index higher than 240 toward other trypsin-like proteases such as tPA, thrombin, plasmin, and FXa.

- Sulfonyl derivatives
-
Sulfonyl derivatives represented by general formula (I), salts of the same, and solvates of both: and application of them as drugs: [wherein R1is hydrogen, hydroxyl, nitro or the like; R2and R3are each independently hydrogen, halogeno or the like; R4and R5are each dependently hydrogen, halogeno or the like; Q1is an optionally substituted saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group or the like; Q2is a single bond, oxygen or the like; Q3is, e.g., a group represented by formula (a): T1is carbonyl or the like; and X1and X2are each independently methylidyne or nitrogen]. These compounds exhibit potent Fxa inhibiting activities and serve as excellent anticoagulants which speedily exert satisfactory and persistent anti-thrombotic effects through oral administration and little cause adverse effects.

- NOVEL SULFONYL DERIVATIVES
-
Sulfonyl derivatives represented by the following general formula (I): Q1-Q2-T1-Q3-SO2-QA and drugs containing the same (wherein Q1 is an optionally substituted, saturated or unsaturated, five- or six-membered cyclic hydrocarbon group, a five- or six-membered heterocyclic group, or the like; Q2 is a single band, oxygen, sulfur, C1-C6 alkylene or the like; QA is optionally substituted arylalkenyl, heteroarylalkenyl or the like; and T1 is carbonyl or the like). These compounds have potent FXa-inhibitory effects and promptly exert satisfactory and persistent antithrombotic effects through oral administration, thus being useful as anticoagulant agents little accompanied with side effects.
