This letter describes the continued optimization of M5NAM ML375 (VU0483253). While a valuable in vivo tool compound, ML375?has an excessively long elimination half-life in rat (t1/2?=?80?h), which can be problematic in certain rodent addiction paradigms (e.g., reinstatement). Thus, we required an M5NAM of comparable potency to ML375, but with a rat t1/2of less than 4?h. Steep SAR plagued this chemotype, and here we detail aniline replacements that offered some improvements over ML375, but failed to advance. Ultimately, incorporation of a single methyl group to the 9b-phenyl ring acted as a metabolic shunt, providing (S)-11 (VU6008667), an equipotent M5NAM, with high CNS penetration, excellent selectivity versus M1–4and the desired short half-life (t1/2?=?2.3?h) in rat.

Some new benzenesulfonylthiourea derivatives substituted with phthalazones (2a-q) were synthesized by refluxing the appropriate 4-aryl-1-oxophthalazin- 2(1H)yl benzenesulfonamides with isothiocyanate in dry acetone over anhydrous K2CO3. All the synthesized compounds were characterized on the basis of IR, 1H NMR, MS data and elemental analysis. These synthesized compounds (2a-q) at the dose of 20 mg/kg were tested for antihyperglycemic activity in the glucose-fed hyperglycemic normal rat model and among these compounds 2f and 2m showed modest antihyperglycemic activity.
STUDIES IN THE FIELD OF HETEROCYCLIC COMPOUNDS. SYNTHESIS AND BEHAVIOUR OF 4-(4-CHLORO-3-METHYL)PHENYL-1-(2H)-PHTHALAZINONE TOWARDS SOME ELECTROPHILES AND NUCLEOPHILES

The phthalazinone derivatives 2a-f have been obtained via the interaction of o-(4-chloro-3-methyl)benzoyl benzoic acid with hydrazine derivatives. The behaviour of 2a towards carbon electrophiles and carbon nucleophiles has been investigated. The chlorophthalazine derivative 3S has been also synthesised from the action of PCl5/POCl3 on 2a. The behaviour of 3S towards nitrogen, and oxygen nucleophiles have been also described.
