Scaffold and Parasite Hopping: Discovery of New Protozoal Proliferation Inhibitors

Utilizing a target repurposing and parasite-hopping approach, we tested a previously reported library of compounds that were active against Trypanosoma brucei, plus 31 new compounds, against a variety of protozoan parasites including Trypanosoma cruzi, Leishmania major, Leishmania donovani, and Plasmodium falciparum. This led to the discovery of several compounds with submicromolar activities and improved physicochemical properties that are early leads toward the development of chemotherapeutic agents against kinetoplastid diseases and malaria.

Natural Products as Platforms to Overcome Antibiotic Resistance

Natural products have served as powerful therapeutics against pathogenic bacteria since the golden age of antibiotics of the mid-20th century. However, the increasing frequency of antibiotic-resistant infections clearly demonstrates that new antibiotics are critical for modern medicine. Because combinatorial approaches have not yielded effective drugs, we propose that the development of new antibiotics around proven natural scaffolds is the best short-term solution to the rising crisis of antibiotic resistance. We analyze herein synthetic approaches aiming to reengineer natural products into potent antibiotics. Furthermore, we discuss approaches in modulating quorum sensing and biofilm formation as a nonlethal method, as well as narrow-spectrum pathogen-specific antibiotics, which are of interest given new insights into the implications of disrupting the microbiome.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 288-14-2 is helpful to your research. Reference of 288-14-2

Investigation of corrosion inhibition of mild steel in 1M HCl by 3-methyl-4-(3- methyl-isoxazol-5-yl)isoxazol-5(2H)-one monohydrate using experimental and theoretical approaches

The inhibition effect of 3-methyl-4-(3-methylisoxazol-5-yl)isoxazol-5(2H)-one monohydrate (P1) on the corrosion of carbon steel in 1 M HCl was studied by weight loss, electrochemical impedance spectroscopy (EIS) techniques and potentiodynamic polarization methods. The results showed that isoxazole P1 was a good inhibitor in 1 M HCl and inhibition efficiency increases with isoxazole P1 concentration to attain 93% at 10-3M at 308 K. E(%) values obtained from various methods used are reasonably good agreement. The adsorption of isoxazole P1 obeyed the Langmuir adsorption isotherm. Polarization curves showed that isoxazole P1 acted as a mixed-type inhibitor in HCl. The effect of the temperature on the corrosion behavior with addition of 10-3M of the inhibitor was studied in the temperature range 313-343 K, and the thermodynamic parameters were determined and discussed. In addition, a quantum chemical study suggests isoxazole P1 inhibitor is structurally essential for the protection of metal surface.

6-Substituted 2,4-diaminopyrido[3,2-d]pyrimidine analogues of piritrexim as inhibitors of dihydrofolate reductase from rat liver, Pneumocystis carinii, and Toxoplasma gondii and as antitumor agents

The synthesis and biological activity are reported for 21 6-substituted 2,4-diaminopyrido[3,2-d]pyrimidine analogues (4-24) of piritrexim (PTX) as inhibitors of dihydrofolate reductase (DHFR) and as antitumor agents. Recombinant DHFR from Pneumocystis carinii (pc) and native DHFR from Toxoplasma gondii (tg) were the target enzymes tested; these organisms are responsible for fatal opportunistic infections in AIDS patients. Rat liver (rl) DHFR served as the mammalian reference enzyme to determine selectivity for the pathogenic DHFR. The synthesis of S9-bridged compounds 4-6 was achieved by aryl displacement of 2,4-diamino-6-chloropyrido[3,2-d]pyrimidine (27) with thiol nucleophiles. Oxidation of 4-6 with hydrogen peroxide in glacial acetic acid afforded the corresponding sulfone analogues 7-9. The N9- bridged compounds 10-24 were synthesized from their precursor 3-amino-6- (arylamino)-2-pyridinecarbonitriles via a thermal cyclization with chloroformamidine hydrochloride. Unlike the S9-bridged compounds, the arylamino side chains of the N9-bridged analogues were introduced prior to the formation of the 2,4-diaminopyrido[3,2-d]pyrimidine nucleus. A reversed two-atom-bridged analogue (25) was also synthesized using a synthetic strategy similar to that utilized for compounds 10-24. The IC50 values of these compounds against pcDHFR ranged from 0.0023 x 10-6 M for 2,4-diamino- 6-(N-methyl-3′,4′-dimethoxyanilino)pyrido[3,2-d]pyrimidine (21), which was the most potent, to 90.4 x 10-6 M for 2,4-diamino-6-(4′-methoxyanilino)- pyrido[3,2-d]pyrimidine (12), which was the least potent. The three S9- bridged compounds tested were more potent than the corresponding sulfone- bridged compounds for all three DHFRs. N9-Methylation increased the potency by as much as 17 000-fold (compounds 15 and 21). None of the analogues were selective for pcDHFR. Against tgDHFR the most potent analogue was again 21 with an IC50 value of 0.00088 x 10-6 M and the least potent was 12 with an IC50 of 2.8 x 10-6 M. N9-Methylation afforded an increase in potency of up to 770-fold (compound 15 NH vs 21 N-CH3) compared to the corresponding N9-H analogue. In contrast to pcDHFR, several analogues had a greater selectivity ratio for tgDHFR compared to trimetrexate (TMQ) or PTX, most notably 2,4-diamino-6-[(3′,4′-dimethoxyphenyl)thio]pyrido[3,2-d]pyrimidine (4), 2,4-diamino-6-[(2′-methoxyphenyl)sulfonyl]pyrido[3,2-d]pyrimidine (7), and 2,4-diamino-6-(2′,5′-dimethoxyanilino)pyrido[3,2-d]pyrimidine (14) which combined relatively high potency at 10-7-10-8 M along with selectivity ratios of 3.97, 6.67, and 4.93, respectively. Several analogues synthesized had better selectivity ratios than TMQ or PTX for both pcDHFR and tgDHFR, and the potencies of the N9-methylated compounds were comparable to or greater than that of TMQ or PTX. Selected compounds were evaluated as inhibitors of the growth of a variety of tumor cells in culture. The N9-CH3 analogues were, in general, highly potent with GI50 values in the nanomolar range. The N9-H and S9 analogues were less potent with GI50 values in the millimolar to micromolar range.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.name: 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, you can also check out more blogs about33282-15-4
