Brief Summary: This study will evaluate the safety and tolerability of MK-8150 and its effect on central systolic blood pressure (cSBP) and heart rate corrected augmentation index (AIx) when given as single oral doses in healthy males and in males with mild-to-moderate hypertension. A primary study hypothesis is that post dose mean change from baseline of time-weighted average across 24 hours (TWA0-24hrs) cSBP or AIx is reduced in participants administered MK-8150 compared to placebo in males with mild to moderate hypertension. A mean decrease from baseline compared to placebo of ≥5 mm Hg in TWA0-24hrs cSBP or of ≥5 percentage points in TWA0-24hrs AIx is considered clinically meaningful.

Detailed Description: Up to three planned panels (A, B and C) of either 8 healthy participants or 8 participants with mild to moderate hypertension will be enrolled. For Panel A and Panel B, dosing will occur in an alternating fashion between Panel A and Panel B with dosing commencing in Panel A. Participants will receive alternating single rising oral doses of MK-8150 or placebo in up to 5 treatment periods (Periods 1 through 5). Subsequent doses in any Panel will be administered only after careful evaluation of safety, tolerability, and pharmacodynamic effects of a given dose. For Panel C, participants will receive single rising oral doses of MK-8150 or placebo in up to 5 treatment periods (Periods 1 through 5). Depending on safety, tolerability and hemodynamic effects observed in the healthy participants, Panels A and/or B may be truncated and dosing may proceed in Panel C with hypertensive participants. In this case, dosing of hypertensive participants in Panel C will start with the second highest dose achieved in healthy participants.

Amendment 1 of the protocol added Panel D (healthy males) based on the pharmacokinetic, pharmacodynamic and safety results from Panels A-C. Participants in Panel D will receive single rising oral doses of MK-8150 or placebo in up to 5 treatment periods (Periods 1 through 5) at a dose range of 50 mg to 500 mg of MK-8150. Each treatment period will be approximately 3-4 days apart.

Number of Participants With an Adverse Event (AE)	Up to 14 days after the last dose (Up to approximately 42 days)	An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the study drug. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the study drug, is also an AE.

The length of time spent at an identified cSBP value was defined as the time elapsed since previous post-dose measurement, or time elapsed since drug administration, if there is no previous post-dose measurement.

Change From Baseline in TWA0-24hrs pSBP in Male Participants With Mild to Moderate Hypertension Administered Single Doses of MK-8150 and Placebo (Panel C)	Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16 and 24 hours post dose	pSBP was measured with a validated automatic measuring device. Time-weighted average was obtained as follows: For all pSBP values obtained over the 24-hour observation period, multiply the length of time that the participant spent at each pSBP value by that pSBP value, add these products together, and then divide by duration of the observation period. The length of time spent at an identified pSBP value was defined as the time elapsed since previous post-dose measurement, or time elapsed since drug administration, if there is no previous post-dose measurement.
Change From Baseline in TWA0-24hrs pSBP in Healthy Male Participants Administered Single Doses of MK-8150 and Placebo (Panel D)	Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16 and 24 hours post dose	pSBP was measured with a validated automatic measuring device.

Change From Baseline in TWA0-24hrs pDBP in Healthy Male Participants Administered Single Doses of MK-8150 and Placebo (Panel A)	Pre-dose and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16 and 24 hours post dose	pDBP was measured with a validated automatic measuring device. Time-weighted average was obtained as follows: For all pDBP values obtained over the 24-hour observation period, multiply the length of time that the participant spent at each pDBP value by that pDBP value, add these products together, and then divide by duration of the observation period.
