File No. P7236PC00ENCAPSULATION OF HYDROPHOBIC MOLECULESCROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority from and the benefit of US provisional patent applications Nos. 63 / 715,819 and 63 / 715,825 filed on November 4, 2024, and No. 63 / 843,627, filed on July 14, 2025, the specifications of which are hereby incorporated by reference in their entirety.BACKGROUND(a) Field
[0002] The subject matter disclosed generally relates to processes for the encapsulation of a hydrophobic molecule into a capsule, and more specifically to processes for the encapsulation of a hydrophobic molecule into a capsule formed from biological molecules from biological material of plurality of yeast fermentation bioreactor materials, as well as systems for performing the encapsulation of a hydrophobic molecule into a capsule formed from biological molecules from yeast fermentation bioreactor materials as biological material.(b) Related Prior Art
[0003] Disclosed herein are processes and system for the encapsulation of hydrophobic molecules for formulation developments utilizing molecules from one or a plurality of biological matter of yeast fermentation bioreactor materials to formulate biological capsules encapsulating hydrophobic molecules.
[0004] The delivery of hydrophobic bioactive molecules in water-based media requires emulsification and encapsulation technologies that require surfactant and emulsifier molecules. These molecules make ultra-tiny droplets encapsulating the hydrophobic molecules in a structure that is energetically stable and structurally sufficiently resilient to always be in the state of Brownian Motion or in a colloidal state of suspension in water, without getting stuck to each other, merge, aggregate, precipitate, or flocculate together, or bind to the walls of the container over time. Many commonly used surfactants in emulsification or encapsulation excipients are derived from petroleum-based chemicals and or synthetic molecules, which are often toxic.
[0005] There is a trend for cleaner and greener alternatives to current emulsification and encapsulation systems utilizing these synthetic surfactant and emulsifier. A most preferred solution to this problem would be one completely devoid of any synthetic surfactants or emulsifiers and carrier oils used for encapsulating hydrophobic compounds of interest in current art.SUMMARYFile No.: P7236PC00

[0129] Now referring to examples of encapsulation according to the sequential operational steps to achieve encapsulation of hydrophobic molecules.
[0130] Dried organic solid yeast fermentation bioreactor material such as (i) nutritional food yeast granules, (ii) brewing waste (mixture of grains, yeast and hope leaves) and (iii) dried yeast slurry from one brewing facility wastes and (iv) dried yeast slurry from a second brewing facility wastes were obtained, and they were not grinded or powdered further. In current art, the nutritional food yeast, as well as brewing, are accomplished in varieties of yeast fermentation bioreactors using food sources like sugarcane or sugar beet or fruit extracts concentrates and wide ranges of grains as source of starch and other nutrients.
[0131] The dried organic solid yeast fermentation bioreactor materials were then processed according to the steps of this current invention:
[0132] In step (a) of the process, the said dried yeast fermentation bioreactor materials are added into a first solvent (95% ethanol) sufficient to contact all the biological matter in an air tight vessel. Follows by step (b) where a mild vacuum treatment of -138 kPa, achieved through a vacuum pump. 50 cycles of mild vacuum of -138 kPa, step (b-i) for 2 seconds followed by release vacuum to atmospheric pressure (101.325 kPa), step (b-ii), while the dried organic solid yeast fermentation bioreactor materials and solvent are present in contact.
[0133] In step c of the process, the first solvent having biological encapsulant materials or encapsulant dissolved in first solvent is filtered using microfiltration (2.5 micron followed by 0.45 micron, further followed by 0.1 micron), so as to provide the filtered biological encapsulant. The relative molecular compositions of biological encapsulant materials obtained from the said the said yeast fermentation bioreactor materials are named as Encapsulant 1 , Encapsulant 2, Encapsulant 3 and Encapsulant 4.
[0134] In step d of the process, the anyone of Encapsulant 1 , Encapsulant 2, Encapsulant 3 or Encapsulant 4 having biological encapsulant materials dissolved therein is to be mixed with a solution of a hydrophobic molecules in a second solvent and mixing thoroughly to obtain a homogeneous mixture, as describe in example figures. In step e of the process, a third solvent of aqueous solution (0.1x PBS, pH 7.4) is mixed to the latter homogeneous mixture as describe in the following examples of encapsulations of different hydrophobic molecules.File No.: P7236PC00
[0135] Now referring to Figure 1. Figure 1 shows results of an analysis applying Untargeted Metabolomic Analysis Using Nano-LC-MS / MS to determine SubClasses of molecules present in relative abundance in the above three samples from step c (Encapsulant 1 , Encapsulant 2, and Encapsulant 3), which provide information about biological molecules present as constituents of the said capsule. Samples from step c in the first solvent were separated on a 150 mm x 75 pm Easy Spray™ C18 column (Thermo Fisher Scientific®, Cat No. ES900) using a gradient elution with water and acetonitrile. Samples were loaded onto the column for60 min at a flow rate of 230 nL / min. Soluble biological molecules in said first solvent were separated using a gradient that starts with 100% water and 0% acetonitrile in the presence of 0.1 % formic acid and were separated for 35 min with a gradient to 100% acetonitrile. Separation continued for an additional 10 minutes using 100% acetonitrile. After 5 minutes, it gradually decreased to 0% acetonitrile and 100% water and maintained that ratio for 10. To obtain MS / MS Spectral Data, eluted biological molecules were directly sprayed into a mass spectrometer using positive electrospray ionization (ESI) at an ion source temperature of 250°C and an ion spray voltage of 2.1 kV. The full-scan MS spectra (m / z 80-1200) were acquired at a resolution of 70,000. Precursor ions were filtered according to the monoisotopic precursor selection, with charge state of 1 and 2, and dynamic exclusion of 10s. The automatic gain control settings were 3x106for full FTMS scans and 1x105for MS / MS scans. Precursor ions were isolated using a 2 m / z isolation window and fragmented with a normalized high energy collision of 35%.
[0136] The raw MS / MS Spectral obtained were processed using bioinformatic software and MS / MS databases publicly available. Each data file was uploaded onto the opensource MzMine3™ software for preprocessing. Masses for each sample were detected using a 5.0x105noise threshold limit for both MS1 and MS2 spectra. ADAP Chromatogram Builder, a module of MzMine3, was then used to peak pick based on the following settings: minimum highest intensity 5.0x105and noise of 5.0x105with 5 data points per peak. Once the chromatograms were created, the Local Minimum Resolver module was then used to clean up the features and link the MS1 and MS2 spectra using “MS / MS scan pairing”. The chromatogram threshold was set to 90% with a minimum search range RT of 0.03 and a minimum relative height of 50%. The ratio was 1 .2 and the peak duration was set to 1 minute. Deisotoping was then performed where the retention time tolerance was set to 0.5 mins and the m / z tolerance was set to 5 ppm. The peaks that were in the blank were also subtracted from the sample using the default setting for data points and a fold increase of 150%, meaning that true peaks were identified if the area was 150% more than the noise level. Metabolite annotation was conducted using the opensource Sirius 4 CSI: Fingerid software. The .mgf file of spectral data, exported from MzMine3, was imported into Sirius 4. Default parameters were used for identification, using “Orbitrap” as the type of data and the following database were used: BioDataBase, Biocys, KNApSAcK, Natural products, Plantcys, YMDB and GNPS.File No.: P7236PC00
[0137] To obtain categories of broad classes of molecules present, molecules are identified as metabolite classes present in encapsulants (Encapsulant 1 , Encapsulant 2, and Encapsulant 3) obtained from the yeast fermentation bioreactor materials which consists of varying proportions of yeast and plant materials. The relative abundance of seven categories of molecules identified using a search system called NPCIassifier SubClass structural annotation (based on a Deep Neural Network- Based Structural Classification Tool for Natural Products, as described in J. Nat. Prod. 2021 , 84, 11 , 2795-2807) is presented in Figure 1 , which is a pie charts as percent abundance with a confidence level above 0.3 and a probability higher than 0.9900. The ClassyFire framework organizes molecular entities into a hierarchical ontology: (i) Kingdom level: organic and inorganic compounds, (ii) SuperClass: 26 organic and 5 inorganic categories, (iii) Class: 764 structural categories, (iv) SubClass: 1 ,729 subdivisions encompassing >10,000 compounds, (v) Levels 5-11 : finer resolution based on chemical weight, spanning 910 to 2 entities. The top seven SubClass structural categories are (1) Fatty Acids, (2) Amino acids and peptides, (3) Alkaloids, (4) Terpenoids, (5) Shikimates and Phenylpropanoids, (6) Carbohydrates and (7) Polyketides. In all samples, four categories of molecules are predominantly present: (1 ) Fatty Acids, (2) Amino acids and peptides, (3) Alkaloids, (4) T erpenoids, and are major constituent of the capsule of the present invention.

[0142] According to some embodiments, the capsule has amino acids and peptides levels, may present in both inner and outer parts of the capsule, ranging from about 9 to about 30%, or from about 11 to about 30%, or from about 13 to about 30%, or from about 15 to about 30%, or from about 17 to about 30%, or from about 19 to about 30%, or from about 21 to about 30%, or from about 23 to about 30%, or from about 25 to about 30%, or from about 27 to about 30%, or from about 29 to about 30%, or from about 9 to about 28%, or from about 11 to about 28%, or from about 13 to about 28%, or from about 15 to about 28%, or from about 17 to about 28%, or from about 19 to about 28%, or from about 21 to about 28%, or from about 23 to about 28%, or from about 25 to about 28%, or from about 27 to about 28%, or from about 9 to about 26%, or from about 11 to about 26%, or from about 13 to about 26%, or from about 15 to about 26%, or from about 17 to about 26%, or from about 19 to about 26%, or from about 21 to about 26%, or from about 23 to about 26%, or from about 25 to about 26%, or from about 9 to about 24%, or from about 11 to about 24%, or from about 13 to about 24%, or from about 15 to about 24%, or from about 17 to about 24%, or from about 19 to about 24%, or from about 21 to about 24%, or from about 23 to about 24%, or from about 9 to about 22%, or from about 11 to about 22%, or from about 13 to about 22%, or from about 15 to about 22%, or from about 17 to about 22%, or from about 19 to about 22%, or from about 21 to about 22%, or from about 9 to about 20%, orFile No.: P7236PC00 from about 11 to about 20%, or from about 13 to about 20%, or from about 15 to about 20%, or from about 17 to about 22%, or from about 19 to about 22%, or from about 21 to about 22%, or from about 9 to about 20%, or from about 11 to about 20%, or from about 13 to about 20%, or from about 15 to about 20%, or from about 17 to about 20%, or from about 19 to about 20%, or from about 9 to about 18%, or from about 11 to about 18%, or from about 13 to about 18%, or from about 15 to about 18%, or from about 17 to about 18%, or from about 9 to about 16%, or from about 11 to about 16%, or from about 13 to about 16%, or from about 15 to about 16%, or from about 9 to about 14%, or from about 11 to about 14%, or from about 13 to about 14%, or from about 9 to about 12%, or from about 11 to about 12%, or from about 9 to about 10%, or at least about 9, 11 , 13, 15, 17, 19, 21 , 23, 25, 27 or 29%.EXAMPLE 1ENCAPSULATION OF HYDROPHOBIC MOLECULE CURCUMIN
[0143] Now referring to Figure 2, which is an example of encapsulation using Encapsulant 1 (step c) according to the sequential operational steps d and e to achieve encapsulation of a hydrophobic molecules. The fluorescent hydrophobic molecule used was curcumin (Empirical Formula: C2iH2o06) with molecular weight of 368.385 g / mol and it is almost insoluble in water (less than 8 pg / L at 20 °C).
[0144] In step d, 3.68 ppm of curcumin dissolved in a second solvent (95% ethanol and 5% DMSO) mixed with 4500 ppm of biological encapsulant materials dissolved in first solvent to obtain a homogeneous mixture. In step e of the process, six volumes of a third solvent of aqueous solution (0.1x PBS, pH 7.4) is mixed to one volume of the homogeneous mixture to obtain curcumin encapsulation formulation.
[0145] The resultant formulation of encapsulated curcumin was analyzed using fluorescent spectroscopic analysis. Curcumin is inherently fluorescent (excitation at 420 nm and emission at 570 nm). The above curcumin formulation was subjected to a separation of particles from the soluble parts using a 300 kDa spin-filter. The spin filtration was done at room temperature with centrifugal force of 2000 rpm for 30 minutes. The flow through from the filter having no particles (i.e. , indicating free nonencapsulated curcumin) were collected and the volume was measured. The holding part of the spinfilter having particles was collected and volume adjusted to the original volume by adding the same volume of water as the volume measured for flow through. The samples of flow through and the particles were diluted 10 times in 80% ethanol for spectroscopic analysis (excitation at 420 nm and emission at 570 nm). The dilution in 80% ethanol disrupted all the particles so that encapsulated curcumin was liberated into the solution for fluorescent spectroscopic measurements of relative fluorescent units (RFU) and a concentration curve was constructed to demonstrate linearity of theFile No.: P7236PC00 fluorescent spectroscopic measurements (Figure 2A). Figure 2B shows RFU of 10 times diluted flow- through representing free non-encapsulated curcumin present (RFU 2413) and 10 times diluted encapsulated curcumin present (RFU 38856) in the formulation, which is about 16 time less than the encapsulated curcumin or in other words 16 part out of 17 parts were encapsulated, which is about 94.11 % encapsulation efficiency. The absolute mass ratio of encapsulant molecules to curcumin is about 1300:1 . Figure 2C shows a transmission electron microscopy photograph of the above curcumin encapsulated formulation. Figure 2D, left panel shows particle size distribution as hydrodynamic diameter of the curcumin encapsulated formulation (diluted 50 times in 0.1x PBS) and right panel showing Raw Correlation Data of the above panel indicating good quality data having sufficient particles of homogenous population.EXAMPLE 2ENCAPSULATION OF HYDROPHOBIC MOLECULE CARVEDILOL
[0146] Now referring to Figure 3, which is an example of encapsulation using Encapsulant 1 (step c) according to the sequential operational steps d and e to achieve encapsulation of a hydrophobic molecule. The hydrophobic molecule used was carvedilol (Empirical Formula: C24H26N2O4) with molecular weight of 406.5 g / mol and it is practically insoluble in water.
[0147] In step d, 203.25 ppm of carvedilol dissolved in a second solvent (80% ethanol and 20% DMSO) mixed with 4500 ppm of biological encapsulant materials dissolved in first solvent to obtain a homogeneous mixture. In step e of the process, six volumes of a third solvent of aqueous solution (0.1x PBS, pH 7.4) is mixed to one volume of the homogeneous mixture to obtain carvedilol encapsulation formulation.
[0148] The resultant formulation of encapsulated carvedilol was analyzed using fluorescent spectroscopic analysis. Carvedilol fluorescent (excitation at 254 nm and emission at 365 nm) was measured using similar 300 kDa spin-filter method of Figure 2 Example 1 . The samples of flow through and the particles were diluted 10 times in 80% ethanol for spectroscopic analysis (excitation at 254 nm and emission at 365 nm). The dilution in 80% ethanol disrupted all the particles so that encapsulated carvedilol was liberated into the solution for fluorescent spectroscopic measurements of relative fluorescent units (RFU) and the standard concentration curve was constructed where linearity of concentration shown in dotted line (Figure 3A). Figure 3B shows RFU of 10 times diluted flow-through representing free non-encapsulated carvedilol present (RFU 301) and 10 times diluted encapsulated carvedilol present (RFU 41427) in the formulation and the absolute mass ratio of encapsulant molecules to carvedilol is about 155:1. Figure 3C shows particle size distribution as hydrodynamic diameter of the said carvedilol encapsulated formulation (diluted 50 times in 0.1 x PBS) and Figure 3DFile No.: P7236PC00 showing Raw Correlation Data of the latter sample indicating good quality data having sufficient particles of homogenous population. Figure 3E shows the Raw Correlation Data of the 300 kDa spinfilter flow-through having very poor correlation indicating no particles and results do not meet quality criteria.EXAMPLE 3ENCAPSULATION OF HYDROPHOBIC MOLECULE ANTIMYCIN A
[0149] Now referring to Figure 4, which is an example of encapsulation using Encapsulant 2 (step c) according to the sequential operational steps d and e to achieve encapsulation of a hydrophobic molecules. The hydrophobic molecule used was Antimycin A (Empirical Formula: C24H26N2O4) with molecular weight of 406.5 g / mol and it is practically insoluble in water.
[0150] In step d, 60 ppm of Antimycin A dissolved in a second solvent (95% ethanol and 5% DMSO) mixed with 13810 ppm of biological encapsulant materials dissolved in first solvent to obtain a homogeneous mixture. In step e of the process, six volumes of a third solvent of aqueous solution (0.1x PBS, pH 7.4) is mixed to one volume of the homogeneous mixture to obtain Antimycin A encapsulation formulation.
[0151] The above Antimycin A encapsulation formulation was subjected to a separation of particles from the soluble parts using a 300 kDa spin-filter. The spin filtration was done at room temperature with centrifugal force of 2000 rpm for 30 minutes. The flow through from the filter having no particles (i.e., indicating free non-encapsulated Antimycin A) were collected and the volume was measured. The holding part of the spin-filter having particles was collected and volume adjusted to the original volume by adding the same volume of water as the volume measured for flow through. In another embodiment, the above Antimycin A encapsulation formulation was subjected to dialysis using a 10 kDa dialysis membrane in 30-times excess volume of 0.1x PBS for 6 hours.
[0152] The resultant formulations of encapsulated Antimycin A were analyzed using a liquid chromatography tandem mass spectrometry (LC-MS / MS) method. Only capsule without Antimycin A was used to determine if capsule matrix affects the Antimycin A peak. A 0.1 g of sample formulation materials were extracted in 10.0 mL acetonitrile containing 0.1 % formic acid, followed by a ten-fold dilution in acetonitrile containing 0.1 % formic acid and latter injected in triplicate where the instrumental detection limit was 5 ng / mL with a linear range from 5 to 1 ,000 ng / mL, R2> 0.995. Capsule matrix interference was found to be approximately 1 .6% with Antimycin A (Figure 4A).
[0153] The MS / MS instrument Xevo TQ-S micro was used at parameter setting for this analysis: Electrospray Ionization, Negative mode; Capillary Voltage -1.70 kV, Desolvation Temperature 650°C, Desolvation Gas Flow 1000 L / h Nitrogen, Cone Gas Flow 50 L / h Nitrogen; Collision CellFile No.: P7236PC00Pressure 3.27-10'3torr; Collision Gas Argon. For the parameters for quantitation of Antimycin A the LC- MS / MS instrument was operated in multiple reaction monitoring (MRM) mode and m / z (mass / charge) was determined as 547.2151 , which is in agreement with literature.

The spin filtration was done at room temperature with centrifugal force of 3000 rpm for 20 minutes. The flow through from the filter having no particles (i.e., indicating free non-encapsulated Salinomycin) were collected and the volume was measured. The holding part of the spin-filter having particles was collected and measured to be 2.25 times concentrated to the original volume. In another embodiment, the above Salinomycin encapsulation formulation was subjected to dialysis using a 10 kDa dialysis membrane with four time change of dialysis liquid (0.1x PBS), each 100-times excess volume, once each day for 4 days at 22°C.
