The development of new antimicrobial agents capable of curing drug-resistant bacteria-induced infections is becoming a major challenge to the global healthcare system. To develop antimicrobials with new molecular entities, a series of novel carbazole-based compounds were designed and synthesized by biomimicking the structural properties and biological function of antimicrobial peptides. Compound 29 was selected as a lead compound from the structure-activity relationship analyses and biological activity evaluation. Compound 29 showed excellent antimicrobial activity against Gram-positive bacteria (MICs = 0.78-1.56 μg/mL), poor hemolytic activity (HC50 > 200 μg/mL), and low cytotoxicity to mammalian cells. Compound 29 had fast bactericidal properties and effectively prevented bacterial resistance in laboratory simulations. Antibacterial mechanism studies revealed that compound 29 directly destroyed bacterial cell membranes, leading to bacterial deaths. Importantly, compound 29 displayed an excellent efficacy in a murine bacterial keratitis model caused by Staphylococcus aureus ATCC29213.

A method for enhancing glycemic control and/or insulin sensitivity in a human subject having diabetic nephropathy and/or metabolic syndrome comprises administering to the subject a selective endothelin A (ETA) receptor antagonist in a glycemic control and/or insulin sensitivity enhancing effective amount. A method for treating a complex of comorbidities in an elderly diabetic human subject comprises administering to the subject a selective ETA receptor antagonist in combination or as adjunctive therapy with at least one additional agent that is (i) other than a selective ETA receptor antagonist and (ii) effective in treatment of diabetes and/or at least one of said comorbidities other than hypertension. A therapeutic combination useful in such a method comprises a selective ETA receptor antagonist and at least one antidiabetic, anti-obesity or antidyslipidemic agent other than a selective ETA receptor antagonist.

A new use of darusentan is provided in preparation of a pharmaceutical composition for lowering blood pressure in a patient exhibiting resistance to a baseline antihypertensive therapy with one or more drugs. The composition comprises darusentan in an amount providing a therapeutically effective daily dose; wherein (a) the composition is orally deliverable and/or (b) the daily dose of darusentan is effective to provide a reduction of at least about 3 mmHg in one or more blood pressure parameters selected from trough sitting systolic, trough sitting diastolic, 24-hour ambulatory systolic, 24-hour ambulatory diastolic, maximum diurnal systolic and maximum diurnal diastolic blood pressures. Further provided is a new use of darusentan in preparation of a pharmaceutical composition for lowering blood pressure in a patient exhibiting resistance to a baseline antihypertensive therapy, wherein the composition is administered adjunctively with at least one diuretic and at least one antihypertensive drug selected from ACE inhibitors, angiotensin II receptor blockers, beta-adrenergic receptor blockers and calcium channel blockers.

A method is provided for lowering blood pressure in a patient having clinically diagnosed resistant hypertension. The method comprises administering darusentan to the patient adjunctively with a baseline antihypertensive regimen that comprises administration of at least one diuretic and at least two antihypertensive drugs selected from at least two of (a) ACE inhibitors and angiotensin II receptor blockers, (b) beta-adrenergic receptor blockers and (c) calcium channel blockers. The darusentan is orally administered at a dose and frequency effective, in combination with the baseline regimen, to provide a reduction of at least about 3 mmHg in one or more blood pressure parameters selected from trough sitting systolic, trough sitting diastolic, 24-hour ambulatory systolic, 24-hour ambulatory diastolic, maximum diurnal systolic and maximum diurnal diastolic blood pressures.
