From a high-throughput screen of 42 444 known human kinases inhibitors, a pyrazolo[1,5-b]pyridazine scaffold was identified to begin optimization for the treatment of human African trypanosomiasis. Previously reported data for analogous compounds against human kinases GSK-3beta, CDK-2, and CDK-4 were leveraged to try to improve the selectivity of the series, resulting in 23a which showed selectivity for T. b. brucei over these three human enzymes. In parallel, properties known to influence the absorption, distribution, metabolism, and excretion (ADME) profile of the series were optimized resulting in 20g being progressed into an efficacy study in mice. Though 20g showed toxicity in mice, it also demonstrated CNS penetration in a PK study and significant reduction of parasitemia in four out of the six mice.

As part of a program aimed at the discovery of antinociceptive therapy for inflammatory conditions, a screening hit was found to inhibit microsomal prostaglandin E synthase-1 (mPGES-1) with an IC50 of 17.4 muM. Structural information was used to improve enzyme potency by over 1000-fold. Addition of an appropriate substituent alleviated time-dependent cytochrome P450 3A4 (CYP3A4) inhibition. Further structure-activity relationship (SAR) studies led to 8, which had desirable potency (IC50 = 12 nM in an ex vivo human whole blood (HWB) assay) and absorption, distribution, metabolism, and excretion (ADME) properties. Studies on the formulation of 8 identified 8·H3PO4 as suitable for clinical development. Omission of a lipophilic portion of the compound led to 26, a readily orally bioavailable inhibitor with potency in HWB comparable to celecoxib. Furthermore, 26 was selective for mPGES-1 inhibition versus other mechanisms in the prostanoid pathway. These factors led to the selection of 26 as a second clinical candidate.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 20744-39-2, name is Pyridazin-4-amine, introducing its new discovery. Recommanded Product: Pyridazin-4-amine

BACKGROUND: Commercial compound databases represent rich sources of potential starting points for pharmaceutical and agrochemical product development. Routine insecticidal screening of compounds ordered from these sources led to the identification of a 3-aminopyridyl urea with activity against Myzus persicae (Sulzer) (green peach aphid). Based on this activity and its structural novelty, further exploration of the chemical space around this hit was initiated. RESULTS: A series of ureas based on the structure of the initial hit were synthesized and screened for insecticidal activity. A broad range of tail groups derived from cyclic secondary amines were explored, and many of these compounds were found to be insecticidally active. However, only compounds featuring a 3-aminopyridine or 4-aminopyridazine head group exhibited significant insecticidal potency. Although activity against M. persicae was consistently observed, these ureas were largely inactive against another key sap-feeding insect pest, Bemisia tabaci (Glennadius) (sweetpotato whitefly). CONCLUSIONS: Follow-up of an insecticide hit identified from commercial compound acquisition led to the discovery of a novel class of ureas with activity against M. persicae. Despite considerable effort to identify related compounds with additional insecticidal spectrum, however, activity on other important pests remains limited.

Antifreeze glycoprotein (AFGP) is an O-glycoprotein that displays antifreeze activity through depression of the freezing point of water. GalNAc is a core sugar structure of AFGP, and contributes to induce antifreeze activity of this glycoprotein. However, the general functional role that this sugar plays at the molecular level is still unknown. To elucidate this, it is essential to determine the relationship between structure and activity of O-GalNAcylated AFGP using homogeneous glycoproteins. Thus, the total synthesis of homogeneous O-GalNAcylated AFGP was conducted by using a unique peptide derivative: peptidyl-N-pivaloylguanidine. It was found that peptidyl-N-pivaloylguanidine is an ?unreactive? peptide in peptide coupling reactions but is interconvertible with a ?reactive? peptide-alpha-thioester by means of a simple treatment under buffer condition at pH=7 to 8. The unique switchable reactivity of peptidyl-N-pivaloylguanidine enabled an efficient sequential peptide coupling strategy. By using this strategy, various lengths of homogeneous O-GalNAcylated AFGP were synthesized, including one that was 120 amino acids in length, with 40 O-GalNAcylation sites. The structural analysis by circular dichroism spectroscopy and evaluation of the antifreeze activity of the synthetic AFGP(GalNAc)s revealed that the simple O-glycosylation with GalNAc is essential for both structural and functional basis of AFGP to exhibit antifreeze activity.
